Where plans become necessary...

One situation to where changing plans becomes necessary is when you plan to go on a trip, you and your friend plan to go to universal studios. You plan out what your going to buy, wear, and what rides your going to get on. You plan it a week before on a Friday after school. You and some friends plan to take the bus to universal studios and to get picked up by you parents to stay at the theme park more longer. So after school you and a bunch of friends ride the bus to universal studios, when you get there you do everything as planned. Until in the middle of the trip your mother calls and says that you have to leave early because they can't come and get you because the car broke down. So your furious because now you have to leave early and take the bus home. So you tell your friends and they leave with you. When you get home you guys talk and plan another day but hopefully this time you pray that your plans work out the right way.
