Seriously, people never cease to amaze me.  Since when is it 
ever appropriate to comment on a lady's weight???  Was the woman overweight?  I swear, that comment just might have made me forget my manners...  I would have felt the need to comment on the woman's weight...  but then I have a temper at times.  

  As it has already been said, please don't give this mean person a second thought.  She is just not worth your precious time!
