I set up a pc for my Mom with nothing on the desktop but an icon that say "MAIL" and another that says "NET".
She forgets which button to push to turn it "ON".
I over heard a friend talking to his elderly mother after Church recently. She was concerned that her comp. might get a virus. he told her it wasn't possible because it wasn't online and she's the only one that's on it. She said, oh no, your father uses it too.
