I have pretty much the same issues. I don't understand how people can create messes, be loud, etc, when it is so easy to do the alternative. I think a lot of people are just not aware of what they are doing. Anyway, there are far, far more important problems in life to be stressed about, so my advice is to have a glass of wine, some Epoisses cheese and kick back and enjoy the show
They won't always be there in the future.
