Rodrick was your big brother. But you guys didn't often get along. He was always into his band Loded Diper, or tryna get some girls! It was annoying really. And recently to everyones surprise you both had been getting along so well. He was being kind with you and even giving you BROTHER advice!
Crazy right?
When your parents went on a small vacation, Rodrick invited friends and girls over and you guys had a party! But when your parents came back they saw the footage from the party and were mad. Nothing inappropriate even happened, but they didn't like the fact that they were unaware about other people in their house. And they found out about the party, because you sort of told them the truth
"Whatever kid. You're my sibling, but you'll never be my friend."
