My sister was born when I was three and let just say, I threatened to throw her in the trash can. I think my three year old self thought she was temporary and apparently at that point, I was over it. But I am lucky I have her. So here are somethings you know is true if you have a sister.
She knows your weakest points, and you know hers.
and she'll use that to her advantage when you get in a fight.
She'll probably steal your clothes and you'll probably steal hers.
It's just the cycle, it's how it goes.
She'll want to hang out with your friends.
and she'll complain about being left out constantly.
You threaten to fight any boy that hurts her.
or any girl.
You fight on the daily but you forgive each other without even speaking.
It goes from I hate you to lets get food in under an hour.
