Ex Input:
M: You'll never guess my mom and dad have just decided we're going to live in a village. It's so inconvenient there. ,F: Why have they done that? ,M: Dad says it'll cut our living costs because houses aren't so expensive there, but I don't see it. I mean we'll spend more on petrol getting to the city, won't we? ,F: But your mom and dad work at home and you've got your student card for the bus and it's quiet living there. ,M: Buses don't often go to the countryside nowadays, I'll be stuck out there like with no social life. ,F: Well, how about asking your parents for a motorbike to drive to school? That way they don't have to drive you everywhere. ,M: That's perfect.
