hi, uh, not hi hi, but hi

Coco found my voice recorder, so I'm using it again.
Without it, I wouldn't have recalled a little exchange I had yesterday.
On my way to school, I passed by a double-parked car with a pregnant woman on the passenger side. It was double parked in front of the house of a pregnant woman. The hair color was the same. The car looked different, but hey, whatever. I, therefore, do the lean-down and happy wave only to see a stranger's face awkwardly wave back at me.
Moments like that are always so deliciously awkward because you want to retract the friendly gesture. You want a gesture that says, "Yes, I'm friendly and you're pregnant and that's always a happy thing even if you're uncomfortable because the concept of creating a new life is a happy thing in theory, but I'm sorry I was giving you a familiarly friendly wave when it should have been non-committedly friendly, neutrally friendly, but there we are, we've both smiled and waved so we may as well be friends in a joint-humanity kind of way." But I didn't even have a kid with me at the time and as a sort-of-regular guy that kind of behaviour is just creepy.
With my luck, she wasn't even pregnant.
