A: Do you even know where this bus is supposed to go? B: It should take us all the way up to Altadena. A: Don't you know? B: I'm not positive if it does or not. A: Is this the right bus, or not? B: I have never been on this bus, but I'm sure it's the right one. A: Where are we? This is not Altadena. B: I know, and we've been on the bus forever. A: Tell me what the street signs say. B: Oh my gosh, that one says Temple City. A: Next time, I'll look for the bus myself. B: I know, but now I know the bus that'll take us back.
