Well, I'm clearly not a scientist and this is a blog, not a thesis...
Back in my youth (which was very long ago), I had a need for a resume. I'd only worked a couple of jobs and didn't have much to actually put on a resume; if nothing else, but I am creative.
This time period was pre-computer age, so there were no fancy computers or software to brag about on a resume. So it was fairly common to list your typing speed and any office machines you could operate. I put down the Bostitch M-89 100 Series and the Swingline Model 29886 as machines I had " great competency" in operating. They are -- respectively -- a stapler and an electric pencil sharpener.
Apparently I've a smart ass a long time. So are both of my lovely children. Nature or nurture? Both my babies were doomed from the start.
