Replying to Most stupid thing you've accidentally said to a girl

So I decided that I had to make this thread after I just said the stupidest fucking thing to this girl. So I'm riding on the elevator with this hot ass girl from my dorm floor. On the way up the water that I'm drinking goes down the wrong pipe and I start coughing a fuck ton. By the time we get to our floor I stopped coughing for the most part and we were laughing about it when the girl says "I might have to give you CPR." Being the fucking dumb ass I am, my snap response is "no I'm fine" referring to the fact that I had stopped coughing. While this girl has a boyfriend and most likely didn't mean anything of it the fact that I didn't throw out an "I'd be fine with that" is fucking weak.
