I was walking down the hall the other day and heard one of the young male engineers talking to a female coworker. He was telling her, "yea, my girl friend has one more year of high school before she graduates." The engineer has worked for us for a few years, so I knew he was kidding, and he promptly told his coworker his girl friend was really in her final year of college. But it did get a laugh. Apparently he hasn't gotten the memo that engineers aren't supposed to have a personality or sense of humor. Give him a few more years of corporate life and that will probably take care of itself.
And just for the record, almost all of the engineers seem "young" anymore. Of course it's a relative term.
