This morning I was helping lift an elderly gentleman in hospital and I was chatting a bit as I did so.
Then we went to put the soiled sheets in the laundry.
Colleague turns to me and said in a really exaggerated tone 'Woah. Chill.' I was [ hmm] 'what?' 'Chill. You're babbling. Shush. Just - chill.'
I didn't say a word, just sort of raised my eyebrow.
I wish I'd said don't be so rude or something now - but the moment passed; what would you have said?
