You see these walls in front of me
The ones I use to shield me
Made over time to save me
From what you did
That hurt me
The hope that builds them
Is what also brings them down
It seems like a never-ending story
Where each brick is a reminder of the hurt
That brought them down
These walls are my protection
From the pain that I dread
From each of you
Who I loved
That hurt me bad
