My 10-year-old son Arthur loves to help others. He never __ to help people in need. His favorite pastime is to volunteer __ at various charities in our community. One day, after purchasing the hamburger Arthur liked most, I tried to hurry him along when he __ next to our cur to look at something. I turned to see what stopped him.

Standing about five feet away was an old __ in rags. Every few seconds he smiled and tried to speak to the people who were walking by. At that moment, he turned around and __ my son watching him. __ I could say anything, he smiled broadly and said, “Hey do you happen to have any spare __?”

Arthur __ his empty pockets and then looked at me briefly. I shook my head---I hardly ever carry cash anymore. Arthur __ and then he said something that took my breath away.

“No, I don’t. But are you __? Do you like the hamburger?”

Knowing the old man was hungry, Arthur’s whole face __. “Good, here, you can have __.”

I thought about how many people had __ this man as he walked the streets that day. How many chose to act as if he hadn’t existed? But my son? The one who just moments before had loudly begged me for the hamburger was now __ giving his favorite away to a strange man because he was hungry. And he didn’t __ give the food and walk away. He engaged the man in a conversation. The smile on the man’s face told me this was the real __ for his happiness.

‘‘I’m really proud of you, Arthur. I think you __ his day.”

His __ was beyond my expectation. “It’s only __.”
