So the guy across the street a couple doors down comes over this morning at 8:30 and asks me for some common courtesy. I was sanding my car preparing for paint with an orbital sander. He said it's rude to do that at 8:00 am on saturday morning.
I was shocked that he was so irritated that he came over to ask that. I started sanding at 8 but could have started earlier. I didn't want to too early. SO I said "I don't want to make your family uncomfortable so I'll stop till a little later but don't come over and ask for common courtesy when It's 8:30. It's not 11pm or 6 am, that's rude not 8am". He didn't agree.
So am I wrong and I am rude sanding at 8am Saturday morning?
