I have upstairs neighbours and I can literally hear everything down to what room each individual is in.
The parents can't control their 4 year old son. He screams and shouts at them constantly and calls them idiots etc and when he doesn't get his way he becomes a mini Incredible Hulk and starts banging the floors for a good 10 mins.. and this is almost everyday. He also spits at them. They tell him to stop and he continues
Also they make their child go to sleep at 5Am in the morning and throughout the whole night the kid bangs and runs like it's 1pm in the afternoon.
They used to make their child go to bed at 3am and wake up for nursery the following morning quite often as well..
I'm just wondering as I'm not a parent but I come from a family of over 10 siblings and I've never experienced this with my lil brothers and sisters
