Sister

A wild beast that made its soul purpose to annoy brothers to death and beg for money. If you have one of these creatures you know what I mean. Occasionally they get you out of a tight spot from your parents.

Bro 1: My parents adopted a sister today.
Bro 2: You're dead bro.

Ava

Ava is the nicest person you will ever meet. She will go out of her way for you even if she has just met you. Ava might not be the best at sports, but she always the first to get done with an assignment. She is kind and funny, not to mention incredibly loyal to her friends. If you know an Ava, become her friend and never let her go. Ava will be there no matter what.

Girl #1: I just met Ava today, and she's awesome. You should come hang out with us sometime.

Girl #2: Sure!
