I live 15 feet away from a Primary school playground and have lived here a very long time, so I am used to the sound of kids.
Some of the kids are hilarious, for throwing plastic balls at the housing officer ( from the climbing frame)so the sound of kids shrieking with delight is always better than the idiot throwing a wobbler and slamming doors!
Your nieghbour is a complete waste of organs and a selfish p...rick because the child is having more fun than he is.
