Dawnyann - what does you being overweight have to do with you insulting other people? Just because you are overweight, it does not give you the right to describe someone else who is overweight as a 'big fat heffer' - call yourself that if you want, but not other people.
I was merely trying to point out that if a scruffy looking overweight person was seen scoffing fish & chips that early in the morning most people would think it was RANK! whereas if it was a smart dressed executive person you saw you prob wouldn't bat an eyelid
Look - see what you did there - you managed to get your point across without being rude & insulting. It wasn't too hard was it :)
