"The song Iris deals with some kind of transference of the female energy because the way I would look at women, from the point I met Ali, was forever changed. It's a big moment, at puberty, you're just discovering girls and this women who brought you into the world leaves you, abandons you. And you think it's your fault, because that's something that kids do. But, of course it's not"
- Bono on Iris
The song 'So Cruel' has been rumoured to be a sort of thing where it would be The Edge singing this to Aislinn, who were divorcing around the time the song was written.
