I had a NYC cop yell across the A Train tracks, "Hey, you can't do that down here". I didn't argue, but I feel like maybe I should have, because people should know what these things are, that they're NOT cigarettes, and that what's coming out of them is NOT smoke. In retrospect, I probably should have been more careful, because I thought I was alone in the station and was puffing away, making no effort to be discreet, and I'm sure it must've looked like smoke.
And BTW, not to get too William Safire on you (R.I.P.), but when you're talking about someone's contact with you and your PV, it's "their", not "there". (as in what's not mine is theirs, and neither here, nor there). Ok, I'm going to stop being a grammar dork now. Thanks for the post.
