I was in elementary school . My class and I were at underwater world , having a great time . It was in the middle of winter and I live in a place that gets very cold during the winter , so I was wearing my most favourite sweater I called it my ktzchen kitten sweater . It was hot pink , green , purple , and yellow with four boxes with a kitten wearing sunglasses in each box . It was very hot in the mall where underwater world was in , compared to the outside temp , so while my class was enjoying a lunch break I took off my sweater and left to use the restroom , leaving my sweater on my chair . Now , I still didn ' t know a lot of English since I had just moved to the United States after living in Germany for the first five years of my life , so when I got to my chair to see that my beloved sweater was gone , it was very hard to describe what it looked like . The staff looked everywhere for it , but no one found it . To this day , I still miss my ktzchen sweater .
