You Don't Smoke Do You?

Today was a beautiful day, so I went just outside my apartment to do some studying while enjoying the weather. As I was sitting there I noticed a man ride up on a bike, stop at the beginning of the sidewalk, look around, and then continued into the apartment complex. About 10 minutes later he came back out, paused at the same spot, and then looked at me, and asked if I smoke. When I politely declined he said, "No problem" and rode off. Now whether he was trying to sell me the weed he couldn't sell his client at our apartment complex, or if he wanted a light or a cigarette, I will never know.
