My Share of the Sidewalk

If your the girl that i know this (the rest of this line is unclear),

Than your more than welcome to my share of the sidewalk.

If your the chick I saw in the tall grass looking at someone through tinted blue glass, than your more than welcome to my share of the sidewalk.

Cause I've never been this close before, to someone who didn't seem to mind. I've never found hellos before, I've only found goodbyes.
