When my little brother threw up in the back seat right next to me, my mom pulled over and I jumped out of the car running down the street.
When my baby cousin spit up while I was holding her, I basically threw her at someone else!
And most recently, when my roommate was coerced to do way too many shots at a party we were having, she said she was going to get sick and I basically ran into the next room. Some of her friends put her to bed, though, and after everyone left, I thought I heard sounds of her throwing up in her room. I didn't go in there like a good roommate - all I could do was call out, "Are you okay?" She didn't answer, and luckily my guy friend called me to say he left his jacket and was coming back. I burst out that my roommate had probably thrown up and asked if he could check on her for me when he got to our place. I told him I had a legitimate phobia of it, and luckily he was very understanding and checked on her for me. The next day she got sick several times, but always left the room to do it, so I was fine being around her.
