The lecture field, as viewed by a speaker, surfeited with many of its aspects. Not a corner is left unexplored, from the qualms of the lecturer before an audience, to after speaking, lecturing with and a pointer, introductions -- and what have they play with the subject planned in advance, traveling, being entertained, hotel rooms, old friends and ex classmates, and finally the family reception at home. It and bites and its phrasing has a freshness and sting that only a hardened of this hard path of life could thus poisonously distill. Entertaining -- for lookers on, some may find the shoe pinches and not be able to ""take it"". As for me, I think it very funny.
