A long time ago, there was a father who had to work far away. He tells his child that if anyone asks him where he is, tell him he's gone. But he was afraid that the son would forget, so he wrote down the paper and then told the child to just give the paper to the questioner. But for the rest of the morning no one came, so that night the boy turned the paper over to see it but accidentally next burned it. The next morning, a visitor came to ask where his father was. the boy was bewildered for a while and then said:

- It's gone

Finally the new visitor hurriedly:

- Ask when

- last night

- why lost

- Fire
