Hey so I know we're in love and all, and that our families don't approve.  I'm going to pretend to die but listen very carefully....I'M NOT ACTUALLY DEAD.  I'm going to take this stuff that makes me fall into a death like sleep.  But I'll be awake in a few hours. I just didn't want you to come find me, get all deperessed, and then kill yourself for real.  
 
Remember, I'M NOT ACTUALLY DEAD.
