I went to see my auntie a while ago and she had just got her first computer.
My auntie sat down (it was already logged on because my uncle had been using it.)
I told her to get used to the mouse by moving it around and trying to click on various things. Without warning she actually picked the mouse from the desk and start moving it around in mid air. Apparently she thought that to move the curser upwards, you had to actually pick up the mouse and move it towards the ceiling.
I just burst out laughing at the look of belwilderment on her face while she was waving this mouse around.
Hope this made you laugh,
