ART OF EDUCATION

Once, there were two children, their parents and grandparents.
They played games, painted the walls, spoke about school, and all things cool.
Then one day, everyone needed to stay at home.
They missed many people and many things. They imagined how it was like in class and what
everyone and everything was doing. So they sent them letters.
Then, one day, something strange happened. They opened their mailbox and saw some letters.
These are the letters that they sent and received.
