I heard friends and strangers saying, "You don't look Arab - what are you supposed to be?" It really is a tired old problem for children of immigrants and kids of mixed race, constantly trying to explain yourself. Eventually, you give up and say, "Okay, what do you think I am?" When you're in the midst of it, you come to understand that "race" is a loose social construct, a series of visual impressions, and that your identity can be whatever the hell crazy thing you want it to be, you just have to grow a sense of humor and cultivate selective deafness.
