If you don't have your facts 
and figures with you I'd remain
silent or wait until they are at 
your fingertips because one 
could lose an otherwise rock 
solid case and look extremely 
foolish in the process. Subsequent 
location of vital documents is easier 
said than done.  The impetus of 
one's argument may well be subject 
to delay  at a later stage and that status 
as a credible advocate might be untenable 
for quite some time to come if not indefinitely 
Please remember this before rushing in to 
any dispute based on oral points alone
Those who can marshal immediate proof
stand a much better chance of swaying 
 doubters and don't knows in our ranks.
