I am better than my sister in every way!
For example, I am better at math. When it comes to rounding I get the correct answer more than half the time, while she gets the correct answer less often.
I even have my own fan base.
Sometimes I wear tights, but not my sister. She is sometimes covered in mites! Gross!
Maybe I'm just jealous though. My sister she is strong and can usually stand on her own, but I always seem to need support lest I fall to her level.
Who am I?
Who is my sister?
