Quoting

Look at us, we cant be alone together cant we?

~Apparently not.

What is that mean? We're supposed to be friends.

~Wow, we arent friends, are we? Not really. We avoid each other. We smile politely. We are two people who pretend to be friends because it would be inconvinient not to.

Well maybe we should stop pretending.

~Maybe we should.

So what do we do now?

~I supposed we eat dinner and then that's it.
