Riddle: You and your 10 friends play frisbee during recess. Every day you and your group of friends are in the same order in a straight line. when the frisbee gets to the end of the line you stop playing and everyone goes back inside. Your best friend always passes it to someone. One day you left the group because you promised your other friend you'd play with her. That day your friend didn't have to pass it, he only had to catch it. When you got back he had to pass it again. How is this possible?
