a)  oh right.  I get it.  I understand what you mean by that phrase 'knowing when you don't know' and you are right, it is like that.

b)  I still don't get it.  I don't understand what you mean by that phrase but I do accept that you mean something by it and I will in all sincerity cease and desist with the 'soft-headed ideas' jibes.  (optional addition would be another go at working out what I do mean if you do want to)

What I have is a good memory, Tarvuist.  But I am not good at bearing grudges or any of that stuff, I am easily pleased - it's like having a chihuahua take offence not a great dane.  all you really have to do is stop with the jibes and I will be happy.  Add a bit of conversation about cooking and I am entertained.

all the best, Lesley
