"And it's you when I look in the mirror
And it's you when I don't pick up the phone
Sometimes you can't make it on your own
We fight all the time You and I...that's alright
We're the same soul
I don't need...I don't need to hear you say
That if we weren't so alike
You'd like me a whole lot more"

Bono has said that after this album, he hoped he wouldn't need to write anymore about his dad, and his relationship with his dad. That's interesting. Link

If your a bloke, and have any sort of relationship with your dad, then like me, you may relate fairly heavily to these lyrics.
Miss you dad, wish I could have said more to you when you were around.
