What do your neighbours do that is perfectly acceptable behaviour but you find really annoying? As in, if you posted about it in AIBU you would be told that YABU but you still find it annoying?
Neighbours opposite have a campervan. They also have a drive. They do not park on the drive, they park their van outside my house instead. They've just come back from a few days away, parked across their own dropped kerb to empty the van, and then moved it to outside my house.
They're not blocking any drives, there's no restrictions on parking. But still, it's annoying me. I can't even explain why it's annoying me. It just is.
