I sit at home, suddenly the electricity is gone and turns on again. At the door and talking. I open, I see a woman standing, with such a business look, and a man of 50.

Hi, who are you and where are you from?

The woman, the chairman said.

Why are you in the shield, you are an electrician?

I am an electrician.

Yes is? Great I say. How many phases in the HRT, for example?

Silence in response.

The man says three!
