Imagine that you are a teacher in a one room school from long ago.
In the room would be many different students.
Some have been there for many years and reached the end of their terms.
They have heard the elementary lessons many times.
Others are only small children, just arriving for their first days.
The older ones will have to help the little children understand the lessons,
And the little children get to hear the lessons that the older students are learning from.
All are there to learn, they all should help each other.
And I suppose there will be a school yard fight once in a while.
But that's the way it is in life.
