Stalking strangers

So, I've taken to following strangers who are smoking.

I was grocery shopping last night and a man in front of me in the parking lot sparked up a smoke. Oh the sweet sweet smell. And without me even realizing it, I started to follow him all the way to his car....which was on the opposite end of where mine was.

So whats next? I sniff random people as they walk by? Huddle on the outskirts of the smokers circle and inhale like there's no tomorrow?

I've become one of 'those' people. Creepy isn't it?
