Mysteries at odd hours

The things you see when you're out and about at 2:30 a.m. are sometimes subtly odd. I was running some late errands, mailing Christmas packages and dropping off some rented DVDs, and was driving toward home when I noticed something peculiar. At the southern edge of the Microsoft campus, standing on the corner at a respectable distance from one another, were two women. They were of that indeterminate age somewhere between middle-aged and elderly, rounded and shapeless, wearing parkas and babushka-style headscarves. They were obviously talking to each other in a genial way, in no particular hurry, standing there in the rain.

What were they doing there? They couldn't have been waiting for a bus; even if they had been anywhere near a bus stop (they weren't), the county buses stopped running at least an hour ago. They obviously weren't in the process of walking home; I sat waiting for the light to change and they showed no signs of stirring or attempting to cross the street in either direction. They were just standing on the corner in the middle of the night, in the rain, talking. For all their lack of defined purpose, they could have dropped there from the skies or grown up from the concrete.

I can't help but think there's a story somewhere in this incident. Did I observe the meeting of two magicians? Are there a couple of statues on campus that are technologically enchanted to come to life at night, and are free to roam around as long as they stay on the campus? Or is it something slightly more prosaic like the Russian Mafia or a roving band of TechnoGrannies?

What strange things have you seen in the wee hours?
