Long ago the gubermit decided they would pay for one year of a two year basic computer course I didn't really need, coz I was already an experienced computer professional. I almost managed to get exemptions on 50% of the subjects.
One of the subjects was Basic Desktop Computing, or how to use Windows and Word. The lecturer, who knew I was an experienced computer professional, took me aside at the beginning of the first class, while every one else was getting settled, and asked me to teach her how to use a mouse.
