This happened to me as well...and I am quite small!! The concierge in the building we lived in asked my son if I was pregnant...and when my son told him "no", and asked him why...he said, "Well, I guess she is just getting fat, then!!" This also happened to be the weekend that I found my first grey hair!!! I was gutted!!! And I am a size 4...so don't feel too bad...apparently some people are just morons!!!
