I recall a conversation I had with a biographer of Sir D.B. (in about 1999 as I recall) and it was clear that the subject of this thread was a VERY difficult fellow to deal with. Yes, he had all the fighting qualities that are rightfully attributed to him but it is clear that he never stopped fighting! Not an easy man. Assuredly interesting but, possibly, not the kind of person you would have invited to a quiet dinner party!
It is oft said that one should not meet one's heroes. I have given up reading biographies or seeing documentaries about people I admire. It's a one way street. I don't think anyone admires me but if they saw a warts and all documentary on me - they certainly wouldn't!!
