explode, really??

I am not sure how it has come to be that it is socially acceptable to comment on the size of a pregnant women. Everyone else can gain or lose weight without the public offering their opinion about how they look. And I am not talking about friends who say things here and there...that is totally fine. If you are my friend than I am fine with you talking about, looking at and even touching my belly. However, if you are someone I don't know at all, please don't comment on the size of my belly, whether you think it is big or small, I really don't care to know. Let me recap where this anger is coming from...a quick grocery run to Publix with a friend from work. We were waiting in the sub line to get her some lunch and this man walks by who is a lot taller than me (not hard to do, btw). He is towering over me and is looking directly at my belly and says outloud "wow, about to explode". Really?? He was clearly looking for a response from me, but I didn't even know where to begin so I chose to ignore him and looked away. Idiot....

A few of my other favorites:
1) when are you due? are you sure there are not twins in there??
2) how much longer do you have left? (me: 3 weeks) oh well they say you do most of your growing in the last month.
3) ohh girl, you must be so hot in this summer heat with that little incubator!
