 So what we're going to do, we're going to take one of the students, Johnson, yeah, you want to get in the bus, and Ms. Selkirk, yeah, you want to get back to your marks. And we're going to present you with situations you'll very often encounter on your buses. All right, Johnson, yeah, you pull your bus in. All right, discharge your passengers. Now, out of the rearview mirror, you'll notice this old woman running for the bus. Yeah, you want to start running, Ms. Selkirk?
