Re-introduction of my cousin Wendy

When my cousin Niu Niu first started English class, her name was Wendy. Then it was Kelly when I saw her 2 years ago. Since then, it has changed to Ann, Angel and now Avril. She wants her next name to be Lady Gaga. Somehow I don't think her teacher would go for that. Anyway, I think of all the names, Wendy fits her the best, so that's what I will call her regardless of what she changes her name to.
