I think what it mostly indicates is a lot of guys get everything wrong. People often think they're being flirted with when they're not, and completely fail to catch when they really ARE being flirted with.
Well, I guess that's what Patr was saying, more or less.
I used to manage a gas station/convenience store combo a few years out of college. At one point, while receiving a drop of fresh fuel at something like 5:30am, the driver of the tanker truck (a woman who appeared to be in her mid-30's or early 40's) came into the station and, while we were waiting for her truck to finish filling the tanks, she says, "Hey, can I tell you a joke?"
"...ok," I reply.
"Ok so hold your hands over your head..." <holds up her hands besides her head like she's being arrested> "...like this."
I do so, feeling a bit silly.
She holds her hands up likewise and steps close to me, palms touching mine, her nose touching my chin. "What's this?" she asks, her breath puffing against my Adam's apple.
"Uh...a chance to smell your perm?" I reply, not catching on.
"No, it's a Polish electric blanket," she explains, and then asks, "Do you know why it's not working?"
"No?" I reply, clearly confused by the question.
"Cuz it's not plugged in," she replies coyly.
"Oh hey, that's pretty clever," I reply (or something like that).
I don't know how long it was until I caught on that she was
probably flirting with me. Hours? Days? I just remember thinking right after that the joke was indeed clever but that the unavoidable component of awkwardness probably canceled the cleverness out.
Ah, to be young and innocent again.
