...When nothing makes a difference, how can you possibly get anything wrong?... 
true, but you couldn't get anything right, then either. fortunately, i know that some things
do make a difference. (that's one reason i like to try different tunas.) but, i am also "brilliant" enough to know when there are, in fact, things that
do not make a difference... like "brilliant pebbles"... and, no, i do not need to actually try them to know it, either!
