One day I visited a friend of mine,Thomas Mouko, who is blind. And because it was night he did something that taught me a lot.

Upon entering the house, Thomas switched on the light.
And I asked him "Thomas, why did you put on the light yet you can't see?"

A thread ............,................. Thomas laughed for a long time, switched off the light and went to the kitchen, after a short while he came with a pot of tea and eggs, placed them perfectly well on the table and switched on the light again
