A
I was raised in a house where my sisters and I weren't trusted by our mother to manage our own appearance. A few years ago, I was home for a visit when my mom, now in her early 70s, called me into her bedroom. We were about ready to leave for dinner. “I don't know what to wear，” She complained. “You girls always look so good. ”
I paused in the doorway and looked at her，wondering if I'd misheard. “What do you mean？” I asked her. “You know what to wear.”“No，” she answered. “ I don't. Can you pick some for me？” I was so surprised.
This was the same woman that, in 1989, told my younger sister she wasn't allowed to leave the house wearing a pair of ripped(撕碎的) jeans; the same woman that, in high school，called me while I was out at a party to ask if my hair was tied up, “You look better with it down，” she told me. Before I could answer I realized, suddenly, that my mother not only wanted my opinion, but needed it. I pulled a pair of blue jeans and a light blue sweater. “Wear this with your black shoes，” I told her. She did. My mother certainly doesn't need anyone to take care of her. In fact, she still cares for my grandmother who lives with her. But with that question, my mother and I started the role reversal(转换) that happens to all parents and all children, from caregivers to receivers.
Now, if I'm visiting or we're together, it's rare for her to wear anything without checking with me first. But every so often, it seems like she asks me just to be able to disagree with my answer and pick out something on her own. And when she does, I just tell her what I think of the way she looks. Sometimes it's “great”， and sometimes it's “awful”．
