Children do indeed help us. Through them, we find our heart and see what is truly important. Yes, that is what it means to be human.
Just a hare more.
Is there anything more uselessly useful than when children “help”? They do help us, though. We help them to become adults, and they help us to become children again. Which is what it means to be human.
“Children are the only really living people.” ~Kenneth Grahame (The Wind in the Willows)
