I'm going to call out my younger brother
What did your brother do that was wrong?
He set my dog on another dog since it happened to bite me
Your brother was only trying to protect you from that rabid dog, don't blame him. He doesn't deserve any hate when he was keeping you safe. You need to appreciate him more instead of seeing the very little negatives in things.
I am not sure. He really made the entire situation wrong. I kind of hate him now.
I think that you should tell him what he did wrong. I think that it is important that you let him know that you do not agree with how he handled the situation.
