Don't forget the meeting that you have to prepare for the meeting; the dreaded pre-meeting. "Hey, Eric, mind if we get together to go over the meeting this afternoon?" And the feared post-meeting. "Hey, Eric, can we chat later about that meeting?" And the email, "Hey, Eric, I missed the meeting. Can you forward me your notes?"

I always like the meeting you have about the meeting, then the follow up meeting a few days later.
