First stranger belly rub

So I always thought that if a stranger touched my belly I would freak out, rude!!! But this weekend I was in line for the restroom and an older lady gently touched my belly and said "you just look so beautiful pregnant. What a blessing to be expecting" and, surprisingly, I didn't feel offended or freaked out at all! Maybe it's because it came with a compliment when I was feeling huge and hot lol. Any other ladies experienced stranger belly rubs yet?
