Tom wouldn't have fallen out of the tree if he hadn't tried to retrieve his frisbee from the highest branch. He wouldn't have tried to retrieve his frisbee from the highest branch if it hadn't been a windy day, and the frisbee wouldn't have gotten stuck up there. He wouldn't have gone outside to play frisbee if it hadn't been for his friend who invited him over for a game. And his friend wouldn't have invited him over if Tom hadn't helped him with his homework the day before.
