Thanks Jools – maybe I need to reassess the Twitter avatar!
Yes it is odd that he wrote to me because as you say I was not the only one to mention him on Twitter. I’ve seen a lot worse about him and his musings on Twitter, but I suppose the point about my original tweet was that it was a question/ponderance that was arguably more interesting/inviting to him than mere abuse.
As you rightly say in your comment just above, Lara, it was one that was invited curiosity because it was rather framed as an open question.
