I'm posting this here because I'll never tell her how disgusting I think she is 
So I was round my friend's house for a cup of tea. Whilst making said tea and chatting, her cat jumped onto the sideboard and began licking the butter in the butterdish. I noticed, pointed it out to friend. She laughed, said 'Oh he's always trying to get the butter' and put the lid back on the butter dish and shooed him away.
She put the lid back on. She didn't throw the butter away. She didn't even scrape the licked butter off fgs.
AIBU to think she's a filthy mare? And to make a mental note to never accept anything with butter on it at her house?
Disclaimer: I am not trying to start a bunfight about the humble butter dish. I am a butter dish advocate. I even own one.
