People can be so weird!
I find that men make the strangest comments sometimes...especially older ones who almost seem like they're trying to be flirtatious. I've had two weird comments by men in the past week:
--I was in the grocery store and some weird man shouted across the way to me "Better not forget the baby food!" Ummmm, yeah.
--Next comment was made by another strange man that came up to me and asked what I was hiding under my shirt.

:
I find that most of these dumb comments come from people who just want to be involved somehow but don't know exactly what to say, so they say whatever pops into their head first!
I had another comment that I found to be borderline rude. The other day I was walking into a restaurant and two other pregnant women were walking in as well. One of them said "Clearly we are a LOT further along than you are, so we get to go first."

: I'm a pretty small girl, and usually people think I'm only 6-ish months along. I thought it was very presumptuous though since in all likelihood I WAS further along than both of them.
