Siblings are people who you might always be mad at or you might love them all the time ( rarely ). They are related to you because you have the same person who gave birth to you or adopted. They can be horrible to each other and they can hate each other..that's fine.
I love his sister,not him.
WAIT..YOU'RE LESBIAN AND YOU LOVE HIS SIBLING?!?!!
No, I'm pansexual and I love his sibling
A person who came from the same parents as you, it can be a girl or a boy, older or younger, it doesn't matter. They're like your best friends, but at the same time, they are obnoxious assholes whose purpose is to ruin your life. Younger siblings tend to be spoiled brats that constantly annoy you, but older siblings tend to make you feel like shit.
But you still love them ;)
