I have just followed this exchange between you both and I wanted to say that it warmed my little penguin heart.

Discussions such as these are the stuff that society is built and continues on. People who don't know each other, exchanging information politely and increasing the sum total knowlwedge of the human race.

I know we're very far removed from my original sardonic and slightly stroppy article, but I'm glad that it managed to generate some good in the world. Keep talking to your grandchildren Christine - and keep talking to strangers Daryl. This is what social media was built to do.
