He's got a long and exciting thirteen weeks ahead of him! I'm quite sure that he is wondering just what the heck he got himself into and he's going to wonder that even more when he finishes his receiving week and picks up with his actual training DI's.

You will be suprised when he comes home on leave to see how much a person can change in a rather short amount of time!

I might recommend the book "Keeping Faith" as a good read while he is away.
