It is good to help the environment by carpooling
Lorna just purchased a brand new vehicle which she can't wait to drive.
Lorna wants to test out the car and see how it drives during her commute.
Lorna offers to drive the carpool this week and her week, so she can try out her car with her coworkers.
Lorna tells her carpool group she won't be joining as its not her driving week, and she wants to drive her new car.
Lorna drives two weeks consecutively and her coworkers are grateful, allowing Lorna to keep the group's favor and test out her new car.
Lorna messes up the carpool schedule with her coworkers and drives her car to work instead, all on her own.
