When my mom came home from the hospital with twins, I was excited at the very beginning. I couldn’t 36 to play with them and be the best big sister ever. Everyone was coming over to our house to hold the babies and 37 presents to the babies and talk nonstop how 38 the babies were. Then they’d pull out their cameras, and just 39 I was about to say “cheese”, they’d run over to my perfectly perfect little brothers and take 40 of them. At that time I was thinking, “Why can’t I be little again so I can be the one getting all the 41 ?” When my aunt Camille got 42 , my mom spent forever finding the perfect clothes for them. On the day of the 43 , my twin brothers had the cutest and prettiest clothes. And then there was me, just sitting and watching in my 44 dress. After the ceremony, all I 45 was how sweet and lovely the twins were. I definitely 46 that they were wonderful, but I couldn’t help feeling 47 and invisible (看不见的). There was a big 48 after the wedding. Aunt Camille and her nice new 49 had the first dance, and then everyone started 50 like crazy including me. I 51 my uncomfortable dress shoes, and I danced and danced and danced! It 52 one of the most fun times I’ve had in my entire life. The very 53 part was when my aunt and I took my twin brothers by the hands and 54 them some dance moves. Teaching them was such a cool thing. I 55 then what a huge waste of time feeling jealous is when you can kick off your shoes and enjoy life!
