In love with a stranger

I See him everyday,
Never even talked to him,
But yet..You know him,
In your mind, you have made up his personality almost,
Casually walking by,
never made eye contact,Just that once
Did he see me?
Does he think the same?
I've never actually stopped to stare but..
I know hes always standing there.
Held that gaze for only a moment..
i wish just once i could talk to him
know what he is thinking
But how could I know, if im in love with a stranger?
