Client: (Monday) I would like a one-on-one training session. 

Me: OK; I can do 2.30 on Thursday. 

Client: Tuesday at that time is perfect. 

Me: No problem. 

Me: (one minute later) Sorry, I’ve just noticed you said Tuesday. I’m afraid I can’t do Tuesday; I offered you Thursday at 2.30.

Me: (an hour later) Just following up. Again, there was a miscommunication and I am NOT available tomorrow. Please let me know if that time on Thursday works for you.

Client: (Tuesday morning) I am looking forward to our one-to-one session this afternoon. 

Me: I’m sorry, I’ve been trying to reach you. That was a mistake. I can still book you for Thursday afternoon. 

Client: (Tuesday, 1:30 PM) I thought it was booked for an hour’s time? 

Me: When we emailed before I offered Thursday, which I think you read as Tuesday. I am not available this afternoon, and can only do Thursday. 

Client: (Wednesday) Well, I guess since you missed our appointment tomorrow will work. What time?  

Me: Again, I’m available tomorrow, Thursday, at 2:30 PM.

Client: OK!

Thursday, 2:30. I show up early for our training session. My client does not show up at all.
