There was a man who had grown old, and his own son had decided to throw him out of the house. "There's no room for you here!" the son said.
The old man wept. "It's cold out there. I'll freeze to death."
The man's son told his own little boy to fetch two blankets, but the boy returned with just one.
"I told you to bring two blankets for your grandfather!" yelled the father.
"I decided to keep one for you when you get old and I throw you out of the house," replied the boy.
Children learn by example.
Inspired by: Mille Fabulae et Una, a collection of Latin fables that I've edited, free to read online. I am not translating the Latin here; instead, I am just telling a 100-word version of the fable.
Notes: This is fable 936 in the book, which is not in Perry's catalog; this is one of the fables of Abstemius.
