The Pina Colada song is an awful song. Have you actually listened to the lyrics? It's about two people who are together, but have never taken the time to actually learn about each other. It's tragic, for example, that they're together, unhappy, and that he doesn't even know that she loves pina coladas and getting caught in the rain, and that she's not into yoga and likes the taste champagne. Has she never told him? Has he never asked? Why are they even together? Moreover, why are they not upset when they run into each other after both have tried to cheat on each other? This is not a song about second chances. This is a reflection of most marriages there days -- short on communication, and heavy on resentment.
This is a song I do not relate to. I make sure that my partner knows exactly what I'm thinking, nearly all the time. Sometimes to my detriment.
