Nice one. Think I did it all using pure logic, although my brain might have filled in the odd gaps as my memory floated back to my first encounter with a mouse.
I remember trying to teach my Dad to use a computer for the first time. With a determined expression on his face, he picked up the mouse and carefully pointed it at the monitor like a remote control for the TV. At first I didn't know what he was doing. Then I laughed 'til I peed myself! I never let him live it down.
