I'm at the hospital, going to visit in my father-in-law and I'm walking down the hallway when I pass a woman emptying the trash cans. I nod and smile and she winks at me.

Later, I head outside to get some air and pass the woman again. I nod, and she winks.

And even later, as I go to leave, I again approach her, from a ways down the hall. Before I can get close enough for nodding range, though, I notice that she's winking at me.

Um.

Is she flirting? She's got maybe a decade on me and I'm got this wedding ring and, I dunno, a hospital doesn't seem the right place to go to pick up men and-- There! She did it again!

And again!

And now I nod and she smiles and we pass and I look over my shoulder and she's winking at the fire extinguisher on the wall. And then at the open door she passes next, and then at a guard walking behind me.

So either she's got a bad eye twitch, or she's really flirtatious.
