One of the biggest complaints I receive, once the weather is warm and we're getting ourselves out into the sunshine with the long, dog days of summer, is those damn neighbors with their weekend parties when all I want to do is sleep because I have to work!
Yes, you can complain, you can call the cops, you can rouse your other neighbors into a violent mob and break down that ungrateful bastard's door and tell him what to do with his damn weekend parties... but I have a better idea.
(Actually I have a lot of great ideas, but here's one for now.)
Give the guy a gift. Make nice with him. Give them these winning lottery tickets. Put them in an envelope with a nice generic note about whatever the celebration might be and wish them well.
Just don't add your name or be seen dropping the envelope off. LOL
