What I mean is, to exes etc? Once you've lost weight and are looking gorgeous, don't you fantasise about strutting your stuff in front of someone who used to put you down for being big? My ex listed my 'faults'..my boobs were ridiculous, my bum was huge, my thighs were flabby...so I would love to see his face when I reach target and he's still same old Mr Bland.
Childish I know 
but wouldn't it be great?
