They fit

Amidst a thousand walls
we exchanged our forevers
I think I found you
and now losing you doesn't scare me as much
I used to lament
over my million pieces
but people are puzzles
not glass
so
you'll be alright
and I promise
never to lose myself again
we are never complete
but you can look through the holes
and see the floor
or you can see the sky
you travel
through my veins
so forever
sounds natural
