Ostrich logic

At the time when Fan, a nobleman of the state of Jin, became a fugitive, a commoner found a bell and wanted to carry it off on his back. But the bell was too big for him. When he tried to knock it into pieces with a hammer there was a loud clanging sound. He was afraid that someone will hear the noise and take the bell from him, so he immediately stopped his own ears.

The story tell us a truth, It's useless for someone to do some wongdoing and he/she doesn't want other people to know this. So if you do a wrongdoing, the others will be known. exvepting that you don't do it.
