Siblings

They are the human form of hell, younger creatures are selfish and watch Morgz. Older ones are selfish. Don’t have siblings

Me: “No you don’t”

Sibling

1. How your parents know where your smut is, when you got that peircing, and how your judgemental grandmother knows that you have a sticker collection on your door.

2. Practice for fighting. They’re easy, but its still fun to see them suffer

My friend: how do you hate your sibling so much?
Me: because he’s always a lil bitch
