I was coming out of the cinema few hours ago, and standing at the bus stop, a couple were making out. I don't even think that they noticed people were starting to line up around them. And if they did, they didn't care.
They must have been no more then 19 years old, both wearing sweaters with local high school logos. Different high schools to boot. A elderly gentleman cleared his throat a few times before tapping them on the shoulder and telling them to wait till they were inside somewhere as there was a group of kids standing about ten feet away.
The group of kids had just come from the movies as well, and looked like some sort of birthday party group.
Reminds me of that one line from the final season of Sex and the City when Carrie makes a comment about almost having sex on a park bench in front of children and Samantha asks what stopped her.
I also remember being like that once. Only it was at night and we were outside the radio station.
