He got to talking with the fellow opposite from him, and I tuned them out, but when the guy next to me made some comment about being able to think with both heads, I cracked up.
My laugh has changed, evidently. I'm doing less of the bwa-ha-ha-hee-hee-hee-snicker-snort-snar
So then the guy across the way, after giving the guy next to me a hard time, started talking about how, seriously, he could tell all sorts of things about a woman from just looking at her. He used me as his object lesson -- I wasn't married, no ring, but he could tell that I was with somebody. Fiance? Boyfriend? I got this look on my face; evidently it was accompanied by a slight flush. "Sort of," I eventually confirmed.
"A fling, then," he said. My grin got bigger. He went on to speculate that I'd gotten some very recently -- last night, perhaps? No? Then more recently than that -- this morning?
"I haven't seen my girlfriend since October," I told him, grinning.
This temporarily broke his brain. I grinned evilly, and left before he'd entirely recovered.
