I was having a smoke on a bench outside of a store where plenty of homeless people may ask for one. So this guy came up and sat down next to me asking for a cigarette. I gave him one, he started smoking and reaching down to his foot. A moment later he put a wet napkin on the table. A white napkin that had the texture of cloth. I noticed he was in distress and had tears in his eyes. That moisture on the napkin could have been chloroform or some shit. I pulled my knife out, kept it hidden yet ready for stabbing, and said "okay, what do you want?" He told me he wanted a smoke but I asked him to leave so he did. I watched him walk away in one direction behind the wall of the store where I couldn't see him and then in the opposite direction out from there. As he was leaving I was breathing heavily. My fingers started to lose feeling and began to cramp up. My nose and upper lip was numb as well. I thought he had done something to me so I dialed nine-one-one and put my phone on the table. A couple minutes past and still couldn't calm down so I hit the green dial. I explained everything to them. What they had told me is that hyperventilation will do that to you however it takes a whole lot more to make you pass out. They understood exactly where I was coming from because they knew my background but eventually I realized how funny that shit was. Wet napkin. Teary eyes. I can't stop laughing. I'm pretty sure if they weren't told who they're about to deal with they would have laughed their asses off.
