I Throught I Knew It All lyrics

Somewhere there's a reason
Why things go like they do
Somewhere there's a reason
Why somethings just fall through
We don't always see them
For what they really are
But I know there's a reason,
Just can't see it from this far

Maybe I don't like it, but I have no choice
I know that somewhere, someone hears my voice
I thought I knew it all
I thought I had it made

How could it end this way?
I thought I knew

Somewhere there's a reason
Why things don't go my way
Somewhere there's a reason
That I cannot explain
Just like the change of season,
Just may not be my turn
But I know there's a reason,
The lesson's mine to learn
