While walking to the village market, Steve and Kynthos saw their neighbor, Mr. Silas, trip over a root and fall face first into a muddy puddle. Mr. Silas was deeply embarrassed but unhurt.
The boys helped him up and continued on to the market after Mr. Silas hurried home to change his muddy cloak.
When they arrived, the baker asked if they had seen Mr. Silas.
Steve, who never filtered his thoughts, immediately blurted out, "Yes, he's incredibly clumsy! He tripped on a root and fell face-first into the mud!" Steve told the truth, but with zero tact or respect for Mr. Silas's privacy.
Seeing the baker look alarmed, Kynthos panicked. He hated when people were upset and wanted to make everyone happy again.
"No he didn't!" Kynthos yelled, waving his arms. "A giant wild boar chased him into the mud! He was being brave!" Kynthos lied, trying to invent a story to protect Mr. Silas's feelings.
Grandfather pulled them aside, troubled by what he had heard.
"Steve, secrets are harmful but other people's privacy is important. Other people's mistakes do not need to be broadcasted by you just because they are true."
"But Kynthos, hiding the truth is a harmful secret. Do not invent lies to cover reality. Knowing the difference is important."
The brothers realized their errors, apologized to the baker, and went to see if they could find Mr. Silas to offer to wash his cloak in the river.
Steve learned to hold his tongue and filter his thoughts, practicing the privacy of the mind, while Kynthos learned that it is better to say nothing at all than to speak a lie.
