You could have given me a million years, and I still wouldn't have come up with the word "limiting" as a less abrasive synonym for the word "immature" . . . but it only took a female colleague thirty seconds to massage my tone in an e-mail to an administrator, with that simple substitution . . . I guess I need one of these "smart thesauruses" implanted in my brain so that I don't extemporaneously say or write anything stupid, but then, of course, I wouldn't be Dave anymore.
