I was thinking something along those lines..... More remembering actually.
Ex wife went on a slimming kick once. I said she didn't need to but you know what wimmin are once they get an idea in their heads...... anywhoo about two months later she asked if I thought she looked better ......, stupidly I said "Yes, that diet has done a lot for you, much slimmer"
"So you really thought I was fat .... etc etc etc" for about a week
