I'm the Adult
A stupid excuse for parents, who think that being an adult makes them have dominance over their kids. (Which it does, unfortunately, but still...)
Kid: Why do you get to call my brother stupid, but I can't? Parent: Because I'm the Adult. Kid: that's not a reas... Parent: (interrupts) I DONT HAVE TO EXPLAIN MYSELF TO A CHILD! BECAUSE IM THE ADULT!
