Generally, in worse areas, more people are going to be carrying though, so I don't think 'f**k off' would be too wise. And especially in America where firearms are a lot easier to get hold of.
Haha, you know that feeling where you feel really shit, and you just want to throw up? I kept getting that, but as I ran downstairs I felt fine. So in the end I used my good mates to get the sick out of me.
You can get drum sticks that are like wire brushes, so the noise isn't as loud. Don't know the proper name, but might be worth having a search around for them.
