Hopefully that just means the younger generation has gotten much more accepting and they don’t see it as a big deal.
I took my little one out for a ride in his stroller recently while wearing a top that made it clear I had boobs. I walked through the local high school parking lot because it’s a nice cut through and is nicer than walking along the road (and is normally empty). About halfway through there was a group of 20-30 high school students out on the grass. I felt uncomfortable walking by, but nobody appeared to give me a second look.
