I'm in a bad mood 'cos I've just got a letter from my Landlord telling me one of my neighbours has complained about the amount of noise I'm making (presumably when I'm playing guitar and singing as I do have a loud voice).

The thing is I'm 90+ % sure I know who's complaining (only one person lives near enough to me to hear the noise that well!) and he constantly plays music at an annoyingly loud volume.

So should I:

a) be mature and disgnified

or

b) be incredibly petulant and write a counter-complaint letter about the volume of his music in revenge?
