If you live in a shared house or an apartment building, it's quite likely you hear your neighbours moving around from time to time.
Sometimes though, they can be just a bit too noisy - a habit that can drive people to post a passive aggressive note, post-it, or printed sign to express their frustration.
These are some of the most hilarious - and occasionally threatening - neighbour notes shared on the internet, compiled by The Poke, a UK humour website.
They might just put you off making any noise from now on.
From car sound systems and not picking up dog pooh to stealing plants, there are lots of angry neighbours out there... and they're not afraid to tell you how they feel.
It might make where you're living far more awkward, but they have provided the internet with a lot of laughs.
