People Touching Your Belly

So many people come up to me and touch my belly! It is weird and very awkward. It is mainly people I do not know at all! I never had the guts to go up to some random pregnant women and touch her pregnant belly without asking! These are some brave people! What if I freaked out on them and said a bunch of rude things! I have touched one of their stomachs back and then they stopped but it is just so awkward! If you are not friends with the person that is expecting don't touch their belly! How would you like random people coming up and touching your gut saying how cute it was. Give the pregnant women her space!
