#5: How Many Times Do I Have to Tell You?
We can only assume from the fact that this poor family member lived to tell the tale that they didn’t consume any of… what was basically a table full of poisonous substances. I’m not sure how serious an investigation they did in this case, but have the police ruled out an attempted homicide by the host?

Maybe we’re being a little bit harsh, and it wasn’t an intended assassination, but it’s possible that the crime of complete and utter lack of consideration is even worse. I’m not sure what I would prefer, going into anaphylactic shock or watching everyone partake in a scrumptious meal while I go hungry.
