I have a very dear friend who I’ve known since I was 18 - I see him sort of sporadically because when he has a girlfriend he’s not allowed to hang out with me (he’s got sort of a thing for jealous types).
So, it’s come to pass that he doesn’t currently have a girlfriend so we’ve been hanging out. Last week we went on a “shopping date” and when he picked me up he had incense going in his car (he’s just an incense in car burning sort of guy). The stick was stuck into the glove box in front of me. We started driving and I noticed that I was getting sort of chesty (I’m asthmatic) and I mentioned it so he ditched the incense.
Great - so we went on our shopping trip and he bought me a mango bubble tea (ummmm, bubble tea, ummmmm) and all was good. We then spent about 25 minutes looking for the car because I wasn’t paying attention when we parked (I never do) and neither did he (which is a bit frightening, since he was driving and all). Anyhow, he was a little stressed out thinking we had lost his car (it turned out that he was looking for the wrong car - he has two and thought we’d brought the other one - again, a lack of attention to detail that’s a little frightening in someone who’s driving…). We found his car and got in and he decided to have a cigarette.
Well, he asked if he could have a cigarette, and of course it’s his car and he picked me up and took me shopping, so I couldn’t exactly say no, right? Besides, how bad could it be? It’s just one cigarette, right? Cool. So he lights his cigarette and starts puffing away. He opened both his window and the sunroof so the smoke would go out. We were driving along, and I’m not totally clear what happened, if a bunch of smoke blew my way, or if my lungs were irritated from the earlier incense deal, or what, but all of sudden I had one of the worst asthma attacks of my life. My lungs literally felt as if they were on fire and I couldn’t inhale any air at all. I was hacking and wheezing - so bad that I could hardly inhale my ventolin. Of course, when that happens, I start to panic (it’s a bit like feeling like you’re drowning), which makes the asthma attack worse.
Friend, of course, is freaking out, thinking that he’s actually killed me or is rapidly about to. He chucks the smoke out the window and opens all the windows and is driving like a crazy person going “What can I do? What can I do?” and I can’t actually speak, so I’m waving him off and wheezing at him. So he pulled over and started kind of pounding my back (I’m assuming to try to help) and that was really quite funny, even though I couldn’t actually laugh, but I stopped panicing, and was actually able to get a bit of ventolin to where it needed to be and actually started to be able to breathe a little. We resumed our trip back to my house with him muttering, “Oh my God, I almost killed my friend. That woman over there thinks I tried to kill you. Oh my God, I almost killed my friend.” ad nausium while sort of rocking back and forth in his seat.
It was the funniest “near death” experience I’ve ever had. 
Mind you, I had a hangover from hell the next day, and had a wheezy sort of cough for the next couple of days, which was a drag, but all in all, very funny.
