"You see kids, friendship is an involuntary reflex, it just happens. You can’t help it." 

Not quite relevant, but interesting. 

• Robin: We can't be alone together, can we?
• Ted: Apparently not.
• Robin: What does that mean? We're supposed to be friends.
• Ted: Well... We aren't friends, are we? Not really. We avoid each other. We smile politely. We're two people who pretend to be friends because it would be inconvenient not to.
• Robin: Well.. maybe we should stop pretending.
• Ted: Maybe we should.
• Robin: So... oh, what do we do now?
• Ted: I suppose... we eat dinner.
• Robin: Yeah.
• Ted: And then that's it.
• Robin: Okay.
