Questions

I'm not sure how to describe this one

I wonder as I scroll this on some old cold concrete wall
Who will read this when I'm done?
The question always sits in the back of my mind as I write.
Will we ever meet or will we forever be strangers?
more questions arise the more I write.
is your life better or worse than mine?
Will you remember my words or forget them when you leave?
who are you?
please tell me or forever I'll wonder.
