I know IABU. Theyre just kids playing. Its lovely weather, they should be enjoying the sun. But from one side I have a football being constantly kicked against a fence (my living room window is outside their back gate) and the other side is the constant bouncing of a basketball going into the net again and again. I think I am a bit sound sensitive anyway, I struggle in shops with loud music, I'm very sensitive to people sniffing/chewing.
