On a hot summer day, my friend and I drove to our friend's house. After two hours' driving, we stopped before a parking lot（停车场）to _______ something to eat there. “It’s _______ treat（款待）," I said, trying to find my wallet in the back seat, but it wasn't there! I _______ the car, but nothing was found. At first, I didn't know _______ I put it.   Then I remembered I left it in the Dunkin Donuts parking lot.

“Oh, thank goodness,” a worker in the parking lot said when I called. "_______ found your wallet lying in the parking lot. We were going through（检查）your _______, trying to find a way to reach you." I told him my address and he sent it back to me without accepting any kind of thanks.

A few years later, my car broke down on a winter night, _______ I had to walk home. Before I left my car, my wallet was still in my pocket. But when I got home, I found it wasn't there. I _______ my wallet again! I was afraid that my good _______ might not go on.

However, good news came the next morning. "Is that Heidi Grosch? We found your wallet in the street." Everything was there and the finder didn't accept any thanks.

I will always be _______ to those who are kind to return my wallet. In return, I will always be ready to lend a hand whenever someone is in trouble.
