I'm not going to attempt to meet my brother
What's the reason that's stopping you?
I'm too busy and the effort of trying to meet him is just not worth it. I dislike him.
You should be there for your brother. You may not get along, but you should attempt to meet them if you already told them you would.
I just don't want to hang out. He gets so annoying.
I get that but you still agreed to hang out with him so you should make good on your promise. When you need him, he'll remember this.
