Alright. I guess this is it. 
I can't believe we're really moving out.- We've lived here for 3 years!
- I know. I'm sad to leave too.
- But hey look on the bright side.
- You're buying your own house!
- And you're moving to New York!
- You're right, we should be happy.
- Hey, thanks for being a great roommate for the past 3 years.
- Yeah you too.
- It was a lot of fun.
- Well, good luck with the new house.
- Thanks. Take care of yourself in New York.
- And don't be a stranger.
- Of course not. The same goes for you.
- Give me a call if you're in town.
- We'll grab lunch or something.
- Will do.
- Okay.
this is it
