Not related to kids but while living in Singapore. My friend and I lived in a 2 bedroom apartment block, most apartments have a gate on them, and in 2 years we had over a dozen visits from neighbours and police because different families were ringing up our neighbours or the police to tell them our door was open (even tho the gate was closed and locked, we just wanted fresh air).

While living in Australia I used to have our front desk remind me to not leave the door open on the deck because “your annoying neighbour keeps calling us to say you left the door open while you were at work”.

I don’t know why people can be so… annoying like that. Like they just sit in their window looking for things to complain about.
