"Sandcastle" lyrics

I saw a house on a shore that was standing tall
And across the water I heard a call
The sound of everything she loved just fell to pieces in the tide

Seasons passed and they shook those walls
Would her heartlast through it all
I waded to my chest, and drowned a little just to watch the fire

So can someone tell me

Why she looks in the mirror thinking it's her fault
When she was the foundation
Ohh - Ohhh - Ohh
I say the words but I know she can't hear me talk
So I just get frustrated
Ohh - Ohhh
Cause I can't watch the sandcastle fall to the ground

I saw a light burning out from across the waves
Try to fix it but I know that can't I change
Life to the way it was before

Cause I know that she
Covers up the scars she's scared to show
And watching doesn't help me let it go
Cause I've been here before but I still don't know

So can someone tell me
Why she looks in the mirror thinking it's her fault
When she was the foundation
Ohh - Ohhh - Ohh
I say the words but I know she can't hear me talk
So I just get frustrated
Ohh - Ohhh
Cause I can't watch the sandcastle fall to the ground

Cause I want to know
If it all crashed down tonight
Would you run towards the riptide
To forget what you can't fight

Cause I want to know
If you couldn't stop the tide
Would you call into the distance
Would you hope that I'm alive

So can someone tell me
Why she looks in the mirror thinking it's her fault
When she was the foundation
Ohh - Ohhh - Ohh
I say the words but I know she can't hear me talk
So I just get frustrated
Ohh - Ohhh
Cause I can't watch the sandcastle fall to the ground
