I would have to call my T if she didn't show-otherwise I'd worry way too much. Oh, I actually did once! The door was locked, and her car wasn't in the parking lot, so I thought she had forgot or something. After stewing about it for 25 minutes, I called and left a message asking if we had a session that day-that I didn't remember her cancelling.

She called me back a few minutes later. She was there, and because she didn't hear me come in, she ran over with her previous client (not on purpose I don't think-more that hearing me come in is a signal that she needs to wrap it up). Turns out the cleaning people locked the door on her, and she walked to work that day.
