Andy- you were at volleyball practice when the ball hit you hard on the head and you trip over another ball and sprain your ankle.
Felix- you were making sandwiches, you were cutting the onion when it burn your eyes and you slam the knife down and it slice your hand.
Jake- you and Jake were playing football barefoot when a broken glass bottle went up in you foot.
Sam- you both were playing hide and seek, you were running when you trip and fall on you face and broke your nose.
