I guess I know...

I guess it came out of nowhere
This realization that I made
I guess I never saw it coming
Oh, how fast the years will fade

I guess I had my head in the clouds
Thinking I have til the end of time
I guess it just caught me off guard
Like a victim blinded to that crime

I guess this is when I live it up
Make every day worth while
I guess I just wasn't sure
Too much time spent being hostile

I guess what I'm getting at
Is I'm sorry for all those days
I guess what you should know
Is that I've tried to walk away

I guess I'm not clear
These thoughts all seem strange
I guess I just wasn't looking
When you decided to change

I know I've messed up
But so have you
I know I've made mistakes
But you did too

I know it's dumb to ask
But where did things go wrong?
I know this game you're setting
But I refuse to play along

I know there's no use in dwelling
What's in the past is in the past
I know you see it too
This is going by so fast

I know you have your doubts
It all fills me as well
I know you still have feelings
It's not that hard to tell

I know that there's no point
But I'm tired of this game
I know we never agree on things
But I'm sick of things staying the same
