פאזל בצורות מיוחדות - Friendship in the glade

If you haven’t got a friend
Your life is sadder, no end.
Friends are good to you and me
Look around and you will see,
In this picture there’s just the same
As if from present life it came.
Guess the secret: who are friends?
We know friendship never ends!
But somebody is angry
He’s sitting rather gloomy.
The puzzle will prompt you, child –
Who should be reconciled?
