Wanna be alone? Great, your sibling will absorb some of the attention from your parents. Your parents aren't all up in your business because their attention has to be divided between y'all. Works for everyone.

Didn't take out the trash? Blame it on them. Left the lights on? You didn't, obviously, it was your sibling. Duh.

Think about it like this: if you're an only child, then you have to wash the dished, clean the house, walk to dog, mow the lawn, take out the trash, do the laundry, and set the table all by yourself! But, with a sibling, that's half the chores, for the small price of putting up with an annoying sibling!

Don't have a phone charger? Need extra cash? Ran out of toothpaste? I mean, you might have to beg, but at least it's there.

What? I didn't fart! I didn't break the blender! I wasn't the one who ate the last cookie! *leads them to believe sibling did it*

Your favorite cousin didn't come to the fam get- together? At a lame party? Or if you and your sibling go to the same school, y'all can be last- resort friends at school. Point is-- you'll always have at least one person who will have to put up with you. Especially if you have dirt on them.
