"I don't believe in luck. I walk under ladders. I'd have 13 tattooed on my arse without any problem. But I do think the universe can turn cold and nasty. I'm never surprised when the worlds get a bit ugly. I'm never surprised when U2 meets resistance".
- Bono, 2015
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.
