I was in college and walking across a big open area called The Plaza (of the Americas, but no one ever said that part). There's a sidewalk running diagonally and there were some guys working on a new walkway along one of the edges.
So I was halfway through the Plaza and one of the guys stopped working, leaned on his shovel, and clear across the space, starting singing the Doors.
I was trying really hard to be all stoic and unaffected by what amounted to cat-calling from construction workers, but because he was not being creepy and because I like the song, I cracked a smile and looked over. He finished the verse, smiled, and said, "You have a nice day, now, miss."
I just smiled, nodded, and kept walking.
