I'm not sure what's confusing you here?
it's all clear now
you wrote bono a letter and he didn't reply
after that your love turned to hate
and now all that hurt is reignited by a random thread on a football forum
all that pain you've kept locked away, hidden, suppressed for so many years that needed an outlet now has one
behind your vitriol we can see that that love for bono still burns as brightly as it did all those years ago when you were younger and much more vulnerable
but that vulnerability still manifests itself as it did all those years ago
you've thought of writing bono another letter but your fragility wouldn't know how to handle another rejection so you languish in a maelstrom of emotions - a mental cage of you own construction
see - i'm not confused one little bit, i understand you perfectly
