If a mute goes into a shop and wants to buy a toothbrush, he shows the shop assistant the action of brushing(cleaning) teeth.
However, if a blind man wants to purchase a pair of sunglasses, what actions should HE show the shop assistant? Tip: Think about this before you answer.....
He opens his mouth and says 'Please can i buy a pair of sunglasses'!!!!
All those of you who got it wrong - turn off your computer and go back to bed!!!!!
