Never mind inappropriate... how about mind-blowingly "please earth, swallow me up NOW!" stupid & idiotic?
22 years ago... on returning home after an all-night party, with a spring in my step, JUST in time for Sunday lunch... seeing my family sitting there with faces as long as you like, feeling really annoyed that as per usual they were being a miserable bunch of sods... plonking myself down into the chair and proclaiming with a giggle "Flippy neck! Who died around here?!"
"Your Mother's best friend's husband"
Ooops
Sunday roast picked at in stony silence.
Not to mention Wannabe homeless by the end of the day!
