My mate Steve, over at Wittering Heights, is going abseiling down a very tall, very public building in the centre of Birmingham.
He is doing this to raise money for blind children.
Once upon a time he was a strapping, hunky young man with a devil-may-care attitude and a seemingly indestructible and well formed body to go with. He still has the attitude.
These days, well he's my age, in his mid forties, with a few creaky bits. Plus he got roped into this and his doctor would probably have a heart attack if he knew.
We are talking typical middle aged boss man, physically speaking.
I guess, having run a friend's reputation into the ground, what I am really trying to say is, more than for some 20 year old, this is a BIG DEAL.
So get over there and promise him at least a fiver - so when he's standing at the top of that building next week and shaking at the knees, he doesn't feel like a prat who's doing this for nothing.
You've been told!
