Cat and Mouse

I never knew how outdated I am where IT is concerned until I went shopping for a new mouse.  I was surprised that these little "mice" now come wireless!  It functions on battery energy and all I need to do is to plug the receiver into the USB port.  Fantastic!  When I got home, I couldn't wait to plug it in.  To my horror, I found that it didn't work!  After fidgeting around and scolding the salesman under my breath, I found that I had forgotten to turn on the switch! Sorry, young man, that's how it is when an old aunty plays with the computer.
