little sister

She has the power to annoy her family, and is very proud about it. She is usually the one breaking the dishes and knocking down cups, and talking back to her parents. Although she may be clumsy, she is very intelligent. They usually have the stereotype to be the troublemaker and the least responsible in the family.

My little sister broke my nails!
My little sister stole my attention.

Big sister

Sometimes a pain in the ass, sometimes someone you never want to talk to again, but other times can make all the bad things that happen go away when its all said and done.

Big sis: Why are you so sad??
Lil sis: Big sister the kids at school are mean
Big sis: aww well I love you!
