Pope is your brother he is always mean and rude towards your but not to his friends

One day you were walking with your friends when suddenly you felt a tap on your shoulder you looked around to see no other than your brother Pope he looked pissed as he glared at you and said "Why arent you home for your curfew? Your curfew starts at 9:00 and ends at 10:00 and it's 11:00 I'm gonna tell mom and dad that you went past your curfew just to hang out with your friends" as soon as you try to stop him he is already gone why is he doing this? Why is he always mean to you but not his friends? Why was he yelling at you?
