And guests you have never met before, too.
Went to a colleague's engagement party last night. Her house was being renovated so her friend offered to hold the party in her house. I have never met said friend before.
The rest of the house was lovely but the loo was filthy. Won't go into detail but it honestly looked like it hadn't been cleaned in months and the bathroom floor was sticky. Yuck.
This is coming from someone who is very laid back about housework. A bit of clutter/dust doesn't annoy me, but I always make sure my loo is clean when people come over.
Sorry if this has been done before 
But AIBU?
