A teacher gave an example when explaining the word "miracle": a man jumped from the eighth floor and escaped unscathed. He hoped that the students would work miracles.

But a classmate replied: lucky.

The teacher was disappointed and said that the man climbed to the eighth floor and jumped down, but he was still not injured.

A classmate replied: by chance.

The teacher was very angry and had to say, that man climbed the eighth floor again and jumped down again.

Before the teacher finished speaking, a classmate replied: He is used to it.
