Living in suburbia, there's only one thing that bothers me. Every day, a few people mow their lawns. I think there should be an official lawn moving day, when everyone does it at the same time. Then all the noise that it creates is at one time. So often, someone mows their lawn, then finishes, then someone else starts. Madness. And people who either kick footballs against walls (thud....thud etc.) or bounce basketballs - this is just such a noisy and annoying thing to do. Bring back borstal.
A word of advice: never set-up or sell anyone PCs.
They will always consider you its creator and will call you, day and night, for as long as the computer is in existence, to ask for help, tell you about problems, error messages, worries, etc. they may have. Unless you charge a retainer fee or have an 090 premium rate number, it is not going to be a profitable experience for you. Be warned!
