There was once a landlord who always pretended he was knowledgeable though he was completely unable to read or write.
One day when the landlord was chatting with his guests, a servant came in and gave him a letter which asked him to lend a cow. The landlord was afraid that
his guests would know he was unable to read or write, so he opened the envelope and glanced over the words. Then he said to the servant, "OK, please tell him I'll go there myself in a few minutes."
