My brother is 5 years older than me.... We are supposed to go on vacation and I REALLY don't want him to go... It hurts my parents but I can't stand him. I hate going to dinner with him or going anywhere with him really. Everyonce in a while, we have a fun moment, but more than anything, he bothers me and I think it's more than a brother sister hate thing. I like having family discussions but when he's there, I hate them. Is it normal that I feel that way? And also, I was really happy when he went away to college and flunked every class.... Normal or not?
