| I was in the queue for the supermarket checkout(付款台) earlier today. All of the checkouts were 1 , and the woman behind me was not happy! Every word that came from her mouth was a(n) 2 ! She wasn't happy with the number of checkouts 3 ; she wasn't happy with the amount of shopping some people had in their baskets; she wasn't happy because this supermarket didn't have a stand where she 4 scan her own shopping. I listened to her 5 looking around as I loaded my stuff onto the conveyor belt (传送带). I didn't want 6 to do with that kind of attitude, and if ever I'd felt like letting someone go 7 of me, it wouldn't be such a woman! But then I 8 back. Standing beside the woman was a five-year-old girl, 9 her granddaughter. The girl's part of the shopping 10 of some comic books. I couldn't 11 it. I pushed my shopping back to the end of the conveyor belt, 12 a space. "After you," I said to the woman and the girl, and 13 them to a big 14 . The woman was delighted, and even 15 to complain - until she was walking away. So, 16 bother having helped? It was because that little girl was probably taking in her granny's complaint like a sponge(海绵). She was learning how to 17 situations like that by listening to her granny. I'd seen that I could interrupt that complaining, and put a smile and some 18 into the middle of it. We can all complain; we can all react 19 , but it doesn't have to be like that. And, even if only for a few 20 , I wanted to leave that little soul with just a glimpse of another way | ||||
