Strangers

I believe that one of the saddest things is when two people who really get to know each other:
their secrets:
their fears,
their favorite things;
what they love;
what they hate;
well, literally everything.

and then something happens; they go back to being strangers.

It's  like you have to walk past him/her and pretend like
you never knew them
never even talk to them before..

when in reality you know everything about them...
inside and out.
