I was reminded of this yesterday - although it happened about a year ago.
Innocently driving home, and about half a mile from the shop, I managed to ram a truck, and although there were no injuries, I managed to write off my car. Friendly canine was on the back seat howling at all the fuss outside. Van driver is not too happy that his truck has a large dent in the side, and the police have arrived to get the street moving again.
In the midst of all this, a man walks up to me with a plastic bag.
"You've save me a trip, I was just on the way to see if you would buy these books"
"Not at the moment, I am a little tied up..."
"Won't you just have a quick look at them"
I shan't type what I said - but he hasn't been into the shop since (And that is no loss !!)
