My mother, who died at the age of 81 from a condition called vascular dementia, could not remember the beginning of a short sentence by the time she was approaching its conclusion, which more or less eliminated from her diminishing world the pleasures of conversation. In the last weeks of her life, the part of her brain that controlled language began to malfunction and she started to speak in weird phrases which, if you listened to them carefully enough, were made up of words and syllables from both English and Yiddish, her first language, which during the long years of her illness she appeared to have completely forgotten.
Her last full, coherent, grammatically intact message to the world was uttered to my sister: "I like your earrings." Her last words to me as mother to daughter, the person she knew to be her daughter and not merely someone she knew she knew, had been stated a few months earlier: "I don't like your hair."
But before she became immobilised by incontinence and other terrible afflictions, the one activity in which my mother was still capable of participating, heart and soul, with a fully functioning mind, was shopping for clothes. She would wander along the street crying and moaning, with me gripping her arm for fear she would fall into the traffic. Her own fate was terrible to her, and she knew it. Then we would get to the small clothing section of the Upper Street [Islington] branch of Marks & Spencer and her identity re-formed; she was a human being once again, capable of assessing the quality of knits and whether this season's hemlines were flattering on her small frame. The shopper's soul-shout, "I want!", raced through her bloodstream. Once, I pointed out that M&S had introduced a delivery service for certain postcodes. "Oh, yeah?" she said. "And you'll pay through the nose for it." But a second or two later she was grasping my arm and asking had I seen the sign that announced that M&S now delivered to certain postcodes.
I took her to buy an outfit for my sister's wedding. As soon as she had ascended the escalator she seized on a Ralph Lauren skirt and Jaeger blouse. She scurried around the store holding fabrics together, "because I've got to match the navy". She cried and stamped her foot when the blouse was too big in the collar, revealing her ruined neck. I understood for the first time that she always wore a little scarf not because her old bones were cold, but because she understood the feminine arts of concealment, how to cover and flatter. She had no intention of being mutton dressed as lamb.
The outfit, which I paid for, cost a bomb. In the taxi back to the home where my sister and I had incarcerated her against her will when she was considered no longer able to function alone, she held her shopping bags with a radiant face, looked at me, eyes milky with innocence and bewilderment. "How are we related?" she asked.
My mother shopped because shopping was what she did and what she was good at. She had an unerring capacity to enter any store and pick out the most expensive item in it; she had a fantastic eye. Even though she almost never had the money to buy the best thing in the shop, she knew what the best thing was, and following on from that, the calculations you needed to make in order to get as close to it as possible: such as when the sales started, or where you could get really good copies, or which secondhand shops had the kind of stock she was looking for.
She had, in other words, taste. And she learned her taste from a variety of sources, such as reading magazines and listening to friends' recommendations, but above all, she spent a great deal of time actually in the shops, looking at things and learning how to discern the good, the bad and the very best. Friends queued up to go shopping with her, for they knew she would take them to the right places and make them try on the things that she knew would suit them.
Poor her, running headlong into the 1960s and a daughter who deliberately frayed the hems of her jeans and wore a handbag made out of a bit of old carpet, instead of Young Jaeger. But, of course, all daughters eventually turn into their mothers, and she had encoded herself inside me already.
Most hostile responses to shopping see it as an act of acquisition, of avarice and greed for things that we do not need but advertising and marketing have made us think we want, a condition that Marx called "false consciousness". We are dupes, and only the strong individualist can hold out against mass consumption. And there are others, of course, who truthfully say that they have no political objection to shopping but they just can't stand it as an activity and regard it as a waste of time.
Against whom I would set those of us who regard it as a pleasure. What does this pleasure consist of, and why do others not experience it; why do they feel, instead, a sense of panic, overwhelmed by what they describe as "too much choice"? Why do I like looking at other people's gardens, while content to allow my own to degenerate into a badly designed, overgrown jungle of strangled plants and rapacious weeds? Because I can't be bothered going out there to do the work of making it bloom. I watch the flowers wither and die from lack of water, and mourn them. But if I wake up and know, at the moment of the mind streaming back from dark into light and consciousness, that what a new navy linen jacket needs is a scarf with a bit of red in it, then I will have ants in my pants until I can get to the shops to find that scarf.
Shopping. A gerund that did not exist before the middle of the 18th century because it did not exist in the way we understand it now. It involved the single revolutionary and emancipatory act of middle-class women with disposable income being able to leave the house. Before this, the goods, or the people who made them, came to the house, either the tailors and seamstresses or the pedlars who sold door-to-door to the poor.
