So let's take last night's example, as that is what led to all this. Lirefighter asked a question about the Tavistock clinic. We both admitted that we didn't know the full details. I found an interesting article which gave some in depth background and I posted that article in a reply. Morqthana clarified an issue. As far as I was concerned, that was a good discussion, where we had all learnt something. But all JohnD was interested in was finding out the extent of Lirefighter's knowledge before we had our discussion. I thought that was very strange, so I then asked why that was important to him. I am genuinely interested in why somebody would be bothered by such things. But to you, that is an example of me sticking my oar in. There's nowt as strange as folk!
