| My elder sister Lisa is only four feet ten, but she has a great personality. I learned everything about 1 from her. She is 2 a brilliant businesswoman. Once she ran nine 3 at the same time just by herself. 4 she talked to her employees, she'd stand on a box. Thus she could look them straight in the eye and 5 connect with them. These days I work in my sister's restaurant. Of course, we quarrel with each other 6 , but I think it's 7 to be open and honest and let things out. 8 God has given us all kinds of senses, we should each have our own 9 and, of course, we can't always 10 with others. One day a woman 11 Vicky was helping me prepare a salad for a cooking class. "You forgot sugar and vinegar," Vicky pointed 12 . "They're used in most salad cookbooks." I 13 to her, "In my family, we don't 14 sugar and vinegar to our salad" She argued,"We do in my family, and our salad is very good." "Yeah? Well, 15 is great!" I shouted back. Back and forth we went 16 we both burst into tears. What are you doing? I asked myself. You became so angry just 17 a recipe! Then I hugged Vicky 18 and she hugged me right back. We've been best friends ever since. Be real; Make 19 with people; Look them in the eye; Tell them how you feel; Don't be afraid to say 20 you mean. When you let go of the feelings you hold inside, you'll be amazed at what comes back to you. | |||
