Does this drive anyone else crazy?

I'm 17w4d and have a baby bump starting. The other day someone randomly came up to me and started rubbing my stomach. It was the most awkward feeling ever. I didn't really know how to respond, but my mother said the look on my face said it all. Some of my friends said this never bothered them, but IMO it's completely ignorant to randomly start touching/rubbing someone that you hardly know. I'm ordering a couple of shirts for work this summer that warn people about touching the bump lol.
