导读：母亲双手从小莫名颤抖，女儿说这是超能力。
　　Last week Bia， my daughter， caught chickenpox. And， because of that， she has to stay alone for a week. So， here I am， spending a whole day， mid-week， at home， watching movies， cooking and trying to make her stay as comfortable as possible， and mine as well.
　　At some point， she looks at my hands and she kindly asks，
　　“So， your hands have this trembling， right？”
　　“Right，” I say， “I have got this since I was a kid.”
　　And it’s true. My hands are shaking， not too much， not too visible and， if I really want， I can control that. Sometimes， when I get caught in the action， maybe my hands are shaking a bit more. When I was a kid， my mom tried to find out why I had this. We went to quite a few doctors， but none of them really “cured” it. They say it was lack of calcium， but when they tested me， I was fine. They also thought it was something psychological， but that didn’t stay true as well. As I grew up， I learned how to live with it. As I said， it’s not something really wrong. It’s very rare to be asked about. I guess most people think I just had too much to drink last night. Or I had too much caffeine. Whatever.
　　“Right，” I say to Bianca again， “I have got this since I was a kid and I never know why I have really got this.”
　　And there she goes， blowing my entire world in just one tiny sentence：
　　“Well， maybe it’s because you have some kind of superpowers.”
