Donny:Come on, we need to buy our subway tickets at that ticket machine.
Cayla:Why can't we just get them at the ticket window?
I'm not sure what the fare is.
Donny:There's a long line and we need to catch a train right now.
Cayla:I've never taken the subway before. I don't know how it works.
Donny:Just follow me.
Here, take this card and walk through the turnstile.
Put your card in this slot and then retrieve it as you pass through.
Cayla:Okay, now where do we go?
Donny:Let's look at this subway map showing all of the lines. That's the station we want.
Cayla:Don't we need to get transfers?
Donny:We don't need transfers to take connecting trains. Let's see, we want the express, not the local train...
Cayla:Are you sure we shouldn't just ask somebody, like a station agent?
Donny:Good luck finding one. And plus, I don't need one.
I can figure it out. Follow me. I think that's the right platform.
Cayla:Are you sure that's the right train?
Donny:Yes, and if you ask me another question, you can continue this conversation with those tracks!
