So, I'm sitting here, annoying USENETizens as usual, and the PHB pokes his head into my office, and asks, "You know, the word, 'weather', like, the weather outside, that's spelled, 'w-e-a-t-h-e-r', right?" "Uh, yes." But the word 'whether', like 'whether or not', that's not the same, right?" I said, yes, they're completely different words, and spelled 'whether' for him, and he left happy.
Sometimes just knowing how to spell stuff can be useful. ;-) (made _me_ feel pretty good, anyway! :-) )
(although, the day he asked "What's a 'neoconservative'?" and I said, "A nazi in a republican suit", he didn't seem to like that very much.)
Cheers! Rich
