Recently, I stopped by a convenience store to get a newspaper and a bottle of drink. The young woman at the check-out counter said, "That'll be five dollars【C1】______please." She then【C2】______down at the paper I was【C3】______and said, "I'm sick and【C4】______all this negative(消极的)stuff on the front【C5】______. I want to read some【C6】______news for a change." She then said, "In fact, I think someone should just【C7】______a Good News newspaper—a paper with wonderful, inspirational【C8】______about people overcoming difficulty and doing good things for【C9】______. I'd buy one every day! " She then【C10】______me for coming in and said, "Maybe we'll get some good news," and she laughed. She made my day. The following day after my business appointments, I【C11】______the same store again to【C12】______bottled water and a piece of newspaper, but a【C13】______young lady was behind the counter. As I checked out I said, "Good afternoon" and handed her my【C14】______. She said nothing—not a word, not a smile or not a gesture. She just handed me my change and【C15】______a negative tone ordered ... "Next! " It hit me right between the eyes: Two people, the same age;【C16】______made me feel great, and the other, well, made me feel that I had inconvenienced her by【C17】______. Every morning, you should ask【C18】______this important question: "Who do I want to be today? 'The Grouch(不高兴的人)' or 'The Good News Girl'"? Your answer will do great good to【C19】______the joy and happiness that you will experience in your【C20】______.
