(since I'm behind ... You're pregnant?! Congrats!! I may have noticed, but forgotten. I know you really wanted another baby)
For me, it's a personal space thing. I don't like people invading my personal space. The only person who was allowed to touch my belly was DP and that's it. I find it rude that people just come up to a pregnant woman and rub her belly. Who do you think you are? Go away. How about I rub your belly. Or better yet, I'll rub your butt and say "Oh it's getting so big!!" How would you like that?
Maybe it's just pregnant hormones, but I don't like it. Of course, my family thinks it's incredibly rude and when I bought a maternity shirt at spencers as a joke (It said "Touch the belly, lose a hand") they gave me these disgusted looks. Because that wasn't rude at all
I dunno .. I just don't like my personal space invaded. Maybe it also had something to do with the fact that my mother kept saying how it was "her baby" and wanted to touch "her baby". That was down right creepy.
I understand many women like it and that's fine. I just don't like it for me.
