Hi Friend

Skipping an appointment is normal. he is just anxious. he can't come to terms about talking his issues to a stranger. just don't make him feel bad that he skipped it. tell him you understand it and encourage him. tell him when he makes up his mind, you'll be glad to fix an appointment and also happy to accompany him on his first visit.

just imagine him being a little kid afraid to go to a kindergarten on his first day.
