     "Ordinary" was the worst word my mother could find for anything. I remember her taking me shopping and

taking no notice of the shop assistants when they suggested that some dress or pair of shoes was very popular-

"We've sold fifty already this week". That was all she needed to hear. "No", she would say, "We're not interested

in that. Haven't you got something a little more unusual?" And then the assistant would bring out all the strange

colors no one else would buy. And later she and I would argue because I wanted to be ordinary but my mother

wanted to be unusual. "I can' t stand that haircut," she said, when I went to the hairdresser with my friend and

came back with a boy haircut, "It's so terribly ordinary." Not ugly, not unsuitable. But ordinary. "Couldn't you

please wear something else?" I asked one day when she was dressing for Parents' Day in tight-fitting bullfighter's

pants and a bright pink sweater. "What's wrong with what I'm wearing? What wasn't wrong with it!" "It's just

that I wish you'd wear something ordinary," I said "something that people won't laugh at. "She looked at me

angrily and then said, "Are you ashamed of your own mother? If you are, Isadora, I feel sorry for you. I really

do."
