[Verse 1]
I built my heart with bricks and stone
A quiet place I call my own
No maps
No keys
No signs
No door
A fortress they can't explore
[Prechorus]
But sometimes I wonder
Sometimes I think
What if the walls weren't so thick?
[Chorus]
I don't let you in
I don't let you see
This heart of mine
Locked up
Set free
I don't let you in
No
Not so fast
This fortress heart
It's meant to last
[Verse 2]
The wind whispers through the cracks at night
I keep the moon at bay
No light
The echoes bounce but never fade
A cage of safety I have made
[Prechorus]
But sometimes I wonder
Sometimes I feel
What if these walls weren't my shield?
[Chorus]
I don't let you in
I don't let you stay
This fortress heart keeps love away
I don't let you in
No
Not today
But what if I gave the key away?
