Oh. Well like I said, if someone bangs on my wall I find it especially rude. And if a neighbor did that to me, I would make no effort to be polite in return and would bang back to show I was annoyed. I would turn the tv down because I am not one for revenges or feuds and the point would have been made.
Funny thing about being considerate. My upstairs neighbors were separated for 6 months due to a job, and when the guy came back, he was very excited to see his girlfriend. I was happy for them (I'm friendly with them both) but I did not want to be up close and personal like that. To make matters worse, it was a night that I had a newborn in my care, who kept getting woken up and was screaming. I couldn't bring myself to interrupt them so I dealt with it and got no sleep. But the next morning, they had slipped a note under my door apologizing "if they had made a lot of noise" and thanking me for being understanding. I like them even more now.
