Today , we had our Code Red drill . It was really really really really dark in there ... I could n't even see my own hand . For a while , I got so bored that I started doing sit - ups , but the ground was too hard and it hurt my back . Well anyways , we got to work , and I played around with Adobe Illustrator , and sucessfully created a cool smiley with a nice yellow gradient .
