I don't mind helping elderly residents with their computer problems if they've been working on something and they get stuck, but I'm not going to sit down and teach you how to use a program from scratch. I don't have the patience and, as previous attempts have shown, the gift of teaching technology to a generation that didn't grow up with it.
