A garden a few door down from me has a screamer. I don't know how old 4 - 8 maybe. It's that high-pitched screech that goes right through you. I maintain that the parents are out of order for failing to teach them not to do this scream. I told mine off for doing it. They stopped, life went and I don't think they're bloody oppressed for that. And parents who don't stop the scream are inconsiderate arseholes.
