That's a good email! Just to be on the safe side, make a hard copy and take it in with you. Just in case. I take absent-minded Ts as par for the course. If she starts out asking you about your week you could say something like you wanted to talk about what you wrote in the email. Then hand it too her.

Every single one of my Ts has been old, one was really old. So maybe my experience with absent-minded Ts doesn't represent usual life.

That was a very nice email. Not pushy, straight-forward, and quite lightly covering info about your flag game so it doesn't even have to be brought up in session out of polite inquiry about what you've been doing. You did good.
