I'm going to go postal on my neighbor.
Why are you so upset at your neighbor?
First, he called to complain about my dog. Second, he's just generally a rude person and annoying.
Sounds like you are very frustrated. It's best to maintain good relationships with your neighbors. They could cause a lot of trouble for you.
I'm going to do what I please.
I really think you should not escalate the conflict any further. If you yell at them or get angry, they will just want to retaliate again against you. Instead, simply ignore your neighbor or calmly explain to them how you are feeling.
