1) Your reaction when your big sister steals your clothing.
My older sister is notorious for "borrowing" my clothes whenever she is home.
2) She just doesn't appreciate affection.
She just doesn't get it.
3) You have to spread out so she won't take your spot.
My sister and I used to fight over one chair in my grandmother's house, and it would be a race to whoever sat there first.
4) When she tries to make you eat something gross.
My sister has a habit of trying to make me eat food she knows I won't like. Like seafood.
5) When you're waiting for her to finish getting ready.
My sister, like many, takes forever to get ready. After she chooses an outfit, she has to make sure her makeup is perfect.
6) When she hurts your feelings.
This is true for the both of us.
7) When things just match up
No matter how much we fight, we are always there for each other in the end.
