Annoying guests thread

[qwertyuiop098]

Inspired by the absolutely cracking annoying things about other people's homes threads, what annoys you about guests at your home?

I'll start - when people stay over because they live too far to travel home after a night out/late dinner...but then overstay their welcome the next day lying in until the afternoon or not taking the hint to get going.

When people leave the toilet seat up.

Making snide comments about my home e.g. MIL "ugh why do you not have any normal milk? I don't like that oat milk!"

Not bringing anything/saying thank you/returning the invitation.

I'm more annoyed when a cousin who lives in Oz and is definitely not going to be coming back to the UK for at least another two years solemnly makes up the bed on the last morning she's here before we run her back to Heathrow.

I don't get why that would be annoying? I would much rather someone made up the bed rather than stripped it. Stripping a made up bed probably takes an extra 5 seconds.
