Unsure if i'm just becoming a miserable old bastard but there's a house that backs onto ours and all the kids do is stand in the garden and scream at each other.
No words, no shouting, no actual game being played... Just stand in the garden and scream at the top of their voices. Sometimes their ma comes out and tells them to "shut the fuck up" but it can go on for ages. It's really bizarre.
If they're playing footy and celebrating scoring then i'd get it, but they aren't?!
