This is a comment I received from a young man on the course held at Trinity, Cambridge, mid-August 2009:

Dear Ralph,

You have probably tired of hearing this by now, but I would like to sincerely thank you for last week. It was a life-changing experience for all of us. I eagerly look forward to next year.

Ollie

To which I replied:

Dear Ollie,

I shall never tire of hearing such lovely remarks. I'm so pleased to have met you, particularly as it has been 100 courses since your father came on the second ever course in 1981! So pleased you'll come next year.

Ralph
