He already has enough of most things though, so what to do?

Donating to his favourite charities is a good idea, and I intend to do that, but what I thought might be nice was if we offered thoughts that are valuable to us in some way. A favourite poem, a saying thats helped us, a nice way of saying we love and appreciate him. Things like that.

I know its unlikely that he will drop in to peruse them, but they will be here for him if ever he wants them.

Thankyou David, just for being, and thanks to everyone who contributes to this.
