My favorite recent personal experience. This was Monday.
I was out for a jog, which is a sight in it of itself. I was crossing a street and noticed a small SUV teetering towards a stop sign, but thought nothing of it. As I passed I heard, "Hey, hey, excuse me."
I stopped, assuming the person needed directions. I turned around..."What's up?"
"You've got beautiful tats."
"Uh, thank you..."
"Do you ever let people photograph you? Would that be something you're interested in?"
"No, that is not something I am interested in."
I then jogged off. This exchange stayed with me the rest of my run. Mainly because I was near the park, and if the guy wanted a mouth fuck, he could've been more direct. I still would have said "no" but I appreciate a candid nature.
