stay together for good (nunca tuve el corazon tan rojo)

indeed, it is possible...

Juno MacGuff: I'm just like losing my faith with humanity.
Mac MacGuff: Can you can narrow that down for me?
Juno MacGuff: I just wonder if like, two people can ever stay together for good.
Mac MacGuff: You mean like couples?
Juno MacGuff: Yeah, like people in love. [...] I just need to know that it's possible that two people can stay happy together forever.
Mac MacGuff: Well, it's not easy, that's for sure. [...] Look, in my opinion, the best thing you can do is find a person who loves you for exactly what you are. Good mood, bad mood, ugly, pretty, handsome, what have you, the right person is still going to think the sun shines out your ass. That's the kind of person that's worth sticking with.
Juno MacGuff: Yeah. And I think I've found that person.

(Juno, 2007)
