Re the trash:
When I lived in Santa Monica many years ago, I discovered that our trash cans were completely full, whereas the neighbor's was half empty, so I used his can. He came out, screaming at me. I explained the situation and that I didn't want to leave the trash, which was neatly tied up in a plastic bag, on the ground where critters could get to it. Apparently he recognized me then and apologized. I couldn't understand why anyone would get upset at someone who was trying to do the responsible thing by stowing their trash in a garbage can. I get upset at people who DON'T stow it.
