TITLE: Reddit, what is the most random event that has happened in your life, that actually ended up saving you from a terrible outcome?
POST: The other night I was at my local bar, and a female was hitting on me.  She ended up getting way too drunk, as did I, and she asked for me to walk her home.  I walked her home, told her I wasn't going in. She then invited me in, to where I walked her to her apartment door.  She then pulled me in after me trying to say I am not coming in. She then decided to strip in front of me, and minutes later started puking.  I then left and went home. Next day, after work, I go back to my local bar, where my bartender friend, working both nights says to me as soon as I walk in, "that girl has herpes."
TL;DR: 
walked drunk chick home, she tried to fuck me. She puked, I left. She ended up having herpes.  Her vomitting kept me disease free.
