I'll be there for you

I'll be the water when you get thirsty,baby
When you get drunk, I'll be the wine
And I wasn't there when you were happy
I wasn't there when you were down
I didn't mean to miss your birthday, baby
I wish I'd seen you blow those candles out...
I'll be there for you
These five words I swear to you
When you breathe I wanna be the air for you
I'll be there for you
I'd live and I'd die for you
I´ll steal the sun from the sky for you
Words can't say what love can do
I'll be there for you!
