You're 20 feet away from a bus stop. There is a bus waiting at the bus stop. You need to get on it, but you're not sure. You remain where you are. The bus idles for a bit, picks up a passenger, and leaves. You have just missed the bus. You now realize the bus takes you to where you want to be, but you were too timid to ask. And so you chase after the bus, on foot. Every now and then, the bus slows down, but you can't get on it. You start to wonder if the bus is slowing down for you, or taunting you. The bus driver rolls down the window and says to you, "I'll stop when this passenger decides to get off the bus." But when is he getting off? The bus driver doesn't care. The bus driver is just enjoying his drive. The passenger is enjoying his ride. Deep down, you know where the passenger wants to go. He wants to go all the way to the final stop, after which, the bus ceases to run. So you start to wonder. You wonder if you will ever get on the bus. Perhaps when the driver wishes to take a break? Perhaps when the bus breaks down? And soon, your legs are giving up. They are tired. They are aching. "Perhaps I should wait for another bus", you think. A very enticing thought. At least you get to take a break. At least your legs wouldn't be in pain any longer. And so you stop. You stop running. You look at the bus going farther and farther away, until it turns at the next city block and disappears. You're regaining your breath. Your legs are beginning to recover. The road is quiet, but that is okay. "More buses will come,", you think. Not long after that, the bus you were chasing after appears again. It has circled the city block and approaches you. It slows down, but the door isn't open, because the passenger is still inside and he isn't getting off.
You have three options:
A) Continue chasing after the bus
B) Stall the bus somehow and drag the passenger off the bus
C) Wait for another bus
