I quarreled with my brother.

I don’t know what about.

One thing led to another

And somehow we fell out.

The start of it was slight.

The end of it was strong.

He said he was right.

I knew he was wrong!

We hated one another.

The afternoon turned black.

Then suddenly my brother

Thumped me on the back

And said, “Oh, come along!

We can’t go on all night-

I was in the wrong.”

So he was in the right. -by Eleanor Farjeon
