Sinister - (meaning the left hand as well as naughty)
A sinister trick is to change your bosses PC mouse setting
to left-hand and then become an instant computer expert when
you fix it for them. It's funny that having set the mouse for left
handed you use the right button to click things...
I am Left Handed by the way and have to live in a world with right-handed sissors.
.... At least we drive on the left in Australia.
