Don't Know Why lyrics

Tide changes sometimes without warning
No explanation here to find
You keep our love from overflowing
And I don't know why
Why must I suffer here in silence
Why do we play these waiting games
With nothing to say
[ Lyrics from: http://www.lyricsmode.com/lyrics/b/bellefire/dont_know_why.html ]
And I don't know why
I need to explain
It's happened again
And I don't know why
When no-one's to blame
It's always the same

Sometimes I may say you're my reason
Something I still believe is true
Just when I think we've gone the distance
You're out of view

I know we've tried
And I'm on your side
Can't you give it time, no need to fight
Say what you like
This thing can fly
I'm running in my sleep, no reason why
This thing can fly
