Ah, this song. It has often occurred to me that the things you share with someone when you first meet them define what you become. In this case, this was once sung in the garden of a hotel in Arles with someone, who, five years later, would fit every lyric perfectly.
Which is why I love the upbeat turn at the end of this song. I feel like Sinead is saying "Woah-oh-oh!" to the thought of looking back. And she's right. I'm done with it.
