There is a joke. I finally saw this life on the bus.

Two brothers were sitting by the fire. The elder brother said, I recently invented a car that uses water instead of oil.

Brother laughed and said, Brother, add firewood! I was mistaken for a genius.

Say confidently: of course.

My brother was a little angry and said, I told you to add firewood.

I'm embarrassed to say, I know, and so are you.

Seeing my mother, my brother took off his shoes and threw them at my forehead.

My brother said angrily, Why? Guess what?
