There is a cow, a lion.
They love passionately each other.
They got married.

They promised to do their best each other.
The cow tried to entertain the lion with delicious grass.
The lion doesn’t like it but endured it.
The lion also tried to entertain the cow with delicious meat.
The cow also doesn’t like it but also endured it.
But they faced with a limitation at last.
They talked face to face.
If you deal a trouble carelessly, it happens to be a big problem.
They argued.
Finally, they separated.

The given last word when they separate was
“I did my best anyway.”
Should they insist on their each point of view, it is as much as the uninhabited island to them.

It is just the cow’s world or lion’s world.
The self-centered thinking,
If you do best ignoring the other person,
It is so much the worse.
