What are some things that sisters fight/argue about?

borrowing clothes without asking, borrowing nail pollish without asking, being in eachothers rooms, reading their personal journals/diarys, using eachothers make up without asking (and taking it to school at stuff -__-) me and my sister always fight about her touching my laptop! (of course i'm 16 and she's 2.....lol.) anddddd what to watch on the TV, who gets to sit by my mom at the resturant(of course this one isnt a big one anymore.) or who gets to sit by my brother in the car (neither is this one. now it's about who gets to sit by the window, nobody wants the middle seat.) sisters fight about a lot of stuff! one copying the other-"i wore my hair like that first!" , "i started to do that before you did" , "you never used to say that before i said it!". and who has to do the dishes, who gets to walk the dog, my sister always takes my cellphone and dials all these numbers and puts it places and forgets where she put it. OH and i have a pet frog and she ALWAYS tries to pull him down off of the shelf he is on and she cries when i don't let her see him or touch him.

Boyfriend/girlfriend ( depending on who they fall in love with ), clothes, rumor at school, other sibling, ext
