Whenever they talk about going to Mexico, I think of a Paul Simon song that has these lines:
Why don't we drive through the night and wake up down in Mexico? I don't know nothing about, nothing about no Mexico... Oh, why, why won't you love me for who I am, where I am. He said because that's not the way the world is baby. This is how I love you baby.
I can't remember the name of the song, but those lines about how we love people in certain ways -- this is how I love you -- rings true for B & S, though the genders are reversed.
