Spelling

Okay, I admit it, I'm (mostly) a grammar and spelling fascist.

So it irritates the hell out of me when I get memos, especially from attorneys, with spelling errors on them.

I mean, c'mon, word processing programs even have these little red squigglies that appear under misspelled words now, so you get a really big visual clue-in that something's not right. Ugh!
