Not so much thread drift as thread over the horizon,stig. Ahem, tho' i went further than you, I still tied it to the thread.

I thought what I just wrote was unfair, then realised that whereas you have gone far afield, i stuck to the subject but went very deep - vertical rather than horizontal.

The thread at least demonstrates that the phrase "the verdict of history" may be pri------tty meaningless.
