I don't have any seriously gross stories, except one time, I went to pick my ex up from work because he was sick and halfway home, I asked if he was okay, and he started to reply that he was fine, then he just started vomiting....in my new car. The shoulder is closed on the interstate so I couldn't stop. I take off my jacket and was like, "Quick! Puke in this!" to soften the blow to my car interior, and the whole way home, he's just puking in my jacket, and my head is practically sticking out the window to avoid the smell.
It was when we got home, that it got really gross, because I have a puke covered jacket, it's like 25 degrees out, and my car is all sorts of nasty, I had to take out the mats and hose them off in freezing weather and clean up the mess by myself. D=
