The One-Question IQ Test

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.

Now if there is a blind man who wishes to buy a pair of sunglasses, how should he express himself? Think about it first before looking at the answer…
Answer:

He opens his mouth and says. “I would like to buy a pair of sunglasses.” If you got this wrong… please go dig a hole, get in it and call it a day.
