Houses make me nervous
They can burn down
Buildings with floors
Have the possibility of collapse
Bridges are unreliable
London Bridge fell after all
But the Mississippi River
Is the one constant of my life
Sitting on its banks
I feel at peace
When leaving, I am not fearful
I know it will be there when I get back
It does not burn, collapse, or get razed to the ground
It is a constant
It is my home
Really like this. The sense of home and permanence from the Father of Waters is felt strongly in your poem.
