My memory is fuzzy – way too fuzzy. Like, what happened when?

At some point in the last few years, I started joking, “Where did you learn that from?” every time he did something a little different in bed.*

He would laugh, I think.
Say something, I think.
And life moved on.

And now that phrase keeps popping into my mind. I can’t quite get it out of there.

I mean, really. Where did he learn that from?
