I consider myself a grammar geek because I like to take at least a little time to make my writing grammatically correct while not sounding stiff. I obviously have my good days and bad days, but either way, it's something I enjoy doing. I sometimes find myself re-reading email over a half dozen times before sending, moving a phrase here, selecting another word there, going between looking at the overall structure and scrutinizing individual clauses. After doing all that and sending the message, I notice that paragraph I forgot to delete which contains just a single unfinished sentence fragment.
