I read this story earlier this morning.
There was once a boy named Bradley. When he was about eight years old, he fell into the habit of thinking of everything in terms of money. He wanted to know the price of everything he saw, and if it didn’t cost a great deal, it did not seem to him to be worth anything at all.
But there are a great many things money cannot buy. And some of them are the best things in the world.
One morning when Bradley came down to breakfast, he put a little piece of paper, neatly folded, on his mother’s plate. his mother opened it, and she could hardly believe it, but this is what her son had written:
His mother smiled when she read that, but she did not say anything.
When lunchtime came she put the bill on Bradley’s plate along with eight dollars. Bradley’s eyes lit up when he saw the money. He stuffed it into his pocket as fast as he could and started dreaming about what he would buy with his reward.
All at once he saw there was another piece of paper besides his plate, neatly folded, just like the first one. When he opened it up, he found it was a bill from his mother. It read:
Bradley sat looking at this new bill, without saying a word. After a few minutes he got up, pulled the eight dollars out of his pocket, and placed them in his mother’s hand.
And after that, he helped his mother for love.
