Co-existing Sisters

This is when your parents make you and your sister, step sister, or half sister get along, but you both hate each other. So you make an agreement that you are going to co-exist, and you call your relationship coexisting, or 'co-existing sisters'!

Lena: I hate you and you hate me, and I don't want to deal with you when I get home from practice and school.

Kate: I hate you, too, and I don't want to be your sister.

Lena: Good, then we are co-existing sisters, because we have to behave but we don't want to be sisters.

Kate: Great! Goodnight, co-existing sister

Lena: Goodnight asshole.

Your sister's cleavage

That thing you try to not look at but a part of you can't look away.

You think you're the only one haunted late at night by your sister's cleavage?
