:: Threaten them with a teacher.
<<defM +5>><<set $threatened = true>><<set $attacked = false>>With more confidence than [[you|You]] feel, you say, "Hey, I don't think you guys should be in here smoking and having sex.  If you take off now, I won't go get a teacher in here."

One of the boys advances on you threateningly.  "Gonna go get a teacher, huh?  You hear that, [[Manny]]?  The new kid's going to get a teacher if we don't knock it off.  You're new here, so maybe I'll give you a pass.  I'm [[Leo]] and this here is Manny and the guy getting his rocks off in the stall is Sean.  And nobody's getting a teacher.  So why don't you just do what you came here to do and scram, okay?"

[[Go get a teacher.]]
[[Threaten them again.]]
[[Go about your business.]]
