There is a mute who wants to buy a toothbrush. By imitating the action
of brushing one's teeth, he successfully expresses himself to the
shopkeeper and the purchase is done.

Think about it first before scrolling down for the answer...
He opens his mouth and says: "I would like to buy a pair of
sunglasses.."
If you got this wrong - please pack up your things, turn off your
