Add to the singing ban
Playing an electric guitar with the amp turned to 11
While very relaxing for yourself, very stressful for the neighbours especially if they, like mine, play the drums on the wall while screaming along...
At least thats what I think they are doing :)
Also you can go out away from the house, so long as you keep your distance from other people... that will help a lot with the stress (and get you away from that neighbour with the electric guitar too)
