I've had two that stick in my mind. OK, so I have a chubby history.
1) From an Ex boyfriend - "you'd have a good figure if you were slim". I dumped him not long after.
2) Over Xmas I was chatting to my brother and he mentioned his Sons Christening about 8 years ago. He had just come accross some of the pictures from it and said to me, "You were a right little tank in those days". Then spent the next few hours grovelling. I wasn't upset by it. At least he didn't say I still was.
Another good one was a few years ago at a posh do. I'd got a fancy frock on, killer heels, full slap, and I'd had my hair done in a different style (put up).
Someone approached me from behind & put their hands on my shoulders. When I turned around the person said
"Oh it's you. You look really sexy.....from behind"
I once went to bed with a gob of moisturiser on my face I hadn't rubbed in. Mr O asked me what it was and I said "Moisturiser....to make me look beautiful."
After a very long pause he said "Big bottle, is it?"
My consultant giving me some urgent stuff to do cause if he gives it to me as opposed to his numpty of a PA that actually runs this particular clinic, 'If I know you're doing it, I can sleep safely knowing it will get done'... Unfortunately I agree with him so I did it.
