Oh God, those have just reminded me of another one. My pal is one of those really loud, bubbly, arm waving, enthusiastic people (I think she was a Labrador puppy in the previous life) and she calls absolutely everyone darling, sweetheart, doll, honey, sugarpuff, my angel, lamb chop, etc etc. If you manage to get through a conversation without at least 20 endearments then you've had a lucky escape. (she's absolutely lovely, by the way!)
Anyway, she'd phoned me at work for a chat one day, and just after I came off the phone, the most senior manager of the Accounts department walked in. He was the dullest, greyest, most serious man ever, and I don't think I'd ever seen him smile.
My brain was still obviously clinging on to the conversation with my pal, and I turned round with a big smile and said "hi honey bun, I'll be with you in a second!"
He actually smiled back, and said "no problem", and from that day onwards I always got a big smile from him, bless him. Even typing this still makes me cringe a bit though, and it was over 20 years ago!
