乘车英语对话-On a Wrong Bus(2)

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.
