A Persian resident of Aksehir received a letter from his relatives in Esfahan. Since he was illiterate, he brought the letter to Nasreddin Hodja to read for him. But the Hodja didn't know Persian.
`This is written in Persian,' he grumbled, `I can't read Persian!'
`Hodja Effendi, Hodja Effendi,' The Persian was very upset, `you are wearing a mountainous turban that signifies your learning, and you can't even read a letter?' Hodja considered for a moment and then took his turban off and handed it over to the Persian.
`Effendi, if it is the turban that does the trick, then be my guest, you wear it and you read the letter!'
