Just because...

This has been running through my head for the last few days:

I'll be there for you
When the rain starts to pour
I'll be there for you
Like I've been there before
I'll be there for you
'Coz you're there for me too...

No one could ever know me
Seems you're the only ones who know
What it's like to be me
Someone to face the day with
Make it through all the rest with
Someone I'll always laugh with
Even at my worst I'm best with you

(with apologies for a couple of liberties taken with the lyrics)
