My old next door neighbour who was elderly and had way too much time on her hands im pretty sure left me multiple letters in my letterbox while she was living there.

I remember getting one telling me to turn down my tv/movie volume at night and telling me to mow the lawn.

Of course none of them were signed either but you could tell it just had to be her.

Not sure what’s worse. The notes in the letterbox or the passive aggressiveness of you meet face to face.

Glad she eventually moved out when she couldn’t look after herself anymore.
