She would
Build walls around herself,
A thousand feet tall.
"Don't trust,
Don't let anyone near,"
She told herself.

But sometimes
She would soften up.
Tear down the walls
And let others in.  

Only to be left,
To be betrayed.
So she would construct them again,
But destroy it soon after.

It was a cycle,
Building walls and then tearing them down,
Over and over again.
