A Different Kind of Memory Problem

As I look back on brass rehearsal last night, I notice something unfamiliar: with two different topics, I had something in my mind, but not in my mental schedule.

In conversation, I mentioned that I would need to leave quickly (because I had another rehearsal to attend). But that need didn't "click" with me until nearly half an hour after rehearsal should have ended, when I suddenly "remembered" that I needed to be rushing out the door.

And on the way out the door, I mentioned to someone that we had brought three new, still-in-the-box music stands with us, but didn't remember until this morning that we needed to unbox and assemble them.

With two different topics, my "autopilot" was working with respect to having critical knowledge available for conversation, but it was broken as far as getting me to understand that I needed to act on that knowledge. I've never noticed this kind of discrepancy before.
