Half asleep I stumble across a tweet from someone called Matt Haig, of whom I have never heard. Apparently, he commented very mildly and reasonably about the role of the press in the short and unhappy life of Love Island presenter Caroline Flack. Arch troll Piers Morgan leapt into twitter action with the kind of response that gets you kicked out of pubs round here on a Friday night.

Intrigued, I look up Haig. He wrote “Reasons to stay alive” about his experience of depression and recovery. Many of the reader reviews are moving and extraordinary. The thread leads me to the Big Green Bookshop – another name I’ve never heard before. 24 hours ago they offered to give a copy of the book to anyone who really needs it and can’t afford to buy one. They have been inundated, not only by people who want the book, but by people who are offering to buy it for a stranger. Its all on Twitter @Biggreenbooks.

I order the book, from Big Green of course, and promise myself that I will buy all my books there in future.

Now I am telling you and soon you will tell someone else.

That’s what we call a relationship-centred business. Everybody comes out well .

Except maybe Piers Morgan.
