IS THIS POSSIBLE?

[trenski]

I was parked at my local park reading the newspaper; all four car windows are tightly rolled up. A stranger walked up to my window; I didn't let the window down or even "crack " it down a little bit. He asked did I have a "light" for his cigarette. I replied no, with the window up and he gave a big sniff and said I didn't me to "scare" you; because I was startled when he came from the back of my car ( without me noticing him) and tapped on the window. Was that "sniff" for me or am I being paranoid. Besides I talked to him with the windows up. Thank You
