Never works quite as well / gets you into big trouble.
Was at my mum’s and Come Dine With Me was on (because it always is). Someone made a semifreddo for dessert. I said “bit stingy to only give everyone half a chocolate frog” (because I’m a twat). My gf laughed. My mum said “what?”
The next few minutes were excruciating.
Too many times to count. I’ll have a think of the worst.
