Rules to survive a horror movie (Suggestions needed)

Tags: 
  1. Don't be a teenager.
  2. Never say: "I'll be right back."
  3. Never ask: "Is anyone there?"
  4. If a killer is following you, never look back or think that he's gone.
  5. Don't try to get in your car in order to escape the killer/monster. The car won't start. For sure.
  6. Don't have sex. [suggested by Critico]
  7. Never go into dark rooms, cellars, etc.
  8. Don't be a good friend. If one of your friends is missing, just try to get out of where you are and don't care for him/her.
  9. If you decide to stay and look for him/her, be sure not to go alone. Go in groups of at least 6 people.

Don't have sex.

sorry is have sex.

What?

I think I can add "Don't have sex", because generally people who have sex in horror films are punished by being killed.
