“Yeah… I always remember what you said
about never throwing them away, about never
closing those doors forever. I remember

Sometimes, even if you have the keys
those doors still can’t be opened, can they?

Even if the door is open
the person you’re looking for
may not be there, Katya"

“You know I came here the night I left
but I didn’t make it past the front door
I almost walked in but I knew that if I did
I would just be the same old Elizabeth
I didn’t want to be that person anymore"
