I've got one nerve left...

And my neighbors are standing on it. Hell, they're dancing all over it! Why do these people insist on revving the engines of their cars for 5-10 minutes before they drive away? I'm trying to work, I don't feel good, and all I hear are engines revving and revving and revving... If I felt better I'd go over there and clock somebody. Of course, if I felt better, it might not be so annoying!
