This has happened twice in the past 3 weeks to me... the most recent today with a friend as she greeted my arrival at a party.
IMO, it's plain bloody rude (excuse language but I'm just fed up!) to say this to anyone, but to a pg woman who may be feeling particularly sensitive about her body shape at the present time it's particulalry insensitive don't you think?
MN crowd support required!! And can anyone think of a cutting retort for the next person that says something like this to me? I'm always too shocked and inwardly upset to say anything back....
