A lady office secretary wrote a small piece in Readers Digest a few years ago telling how one of the blokes from an adjoining room used to wander in,nod hello to her and her colleagues, and then go over to a filing cabinet in the corner,pull open a certain drawer,peer intently into it for several minutes without touching the contents,then reach in briefly,close it without removing anything and stroll nonchalantly out.Later another chap would saunter in and do the exact same procedure before leaving.The two men did this several times a day,every day,and eventually her curiosity got the better of her,so she opened the drawer and saw no paperwork in there at all,just a complete chessboard and pieces of a game in progress! :cool:
