So if you call a tail a paw, how many feet are there? (With apologies to Abraham Lincoln. :-) Walter ---------------- You presume one of the men is a father of someone, a 'paw' as said in the quaint fashion of the hillbilly. For him to be a 'tail' as in one who follows another in a clandestine fashion results in an indeterminate number of feet, as it would depend upon how far, in feet, the 'tail' was determined to follow the subject. There is just not enough information to measure this distance. Please go back to my proof of this matter, previously posted, using entirely scientific data and measurements, with precise mathematical calculations. * To join/leave the list, search archives, change list settings, * * etc., please visit http://raven.utc.edu/archives/hp3000-l.html *
