On my return from Keith’s funeral today, my wife reminded me of a time - probably 25+ years ago - when she ran out of petrol. She had phoned me while i was out collecting waste. I was miles away and couldn’t help. Seems i rang Keith and before too long, he turned up, with a jerry can full of petrol to get her on her way. 
The fact that my wife remembered that gesture - after all this time - is a measure of the man.
