Tell me one thing in yourself that you's sister want to change ??????

I'd like to change my sister's memory. She is 15 years older than me, and there are a lot of things from my own early childhood (when she was in her late teens) that are mysteries and I'd love to know what was going on, and sort them out. Sadly she has erased most of her memories from her own childhood and teens, thus can't answer many of those questions for me.

My temper, very short and bad temper.

Well, it's hard to say what other people think of you especially when they keep it to themselves. I guess one of the things that she wants me to do is to visit her often because she is always the one to do that. I have a lot of family obligations rarely finding the time to see her family. Recently, she is angry because I did not attend her daughter's birthday. Yup, if there is one thing my sister want me to change, that would be the one.
