Moshe, anyone ever tell you about the boy who cried wolf (no disrepect to Wolfishmusings)? What you did was VERY serious, and you should have been suspended. Fire is not a joke, and faking an alarm is actually a criminal act. You could have been arrested.
Forcing the Fire Department to respond to a phony call, might have chalilah resulted in someone else’s death because that fire department was deployed by your school instead of where they were really needed. And you BOAST about this immature act? You think you were a HERO???? Your actions were more like a zero. What a chillul Hashem, if this is not a phony post (which I am tending to think it was)!
I try never to be abrasive or argumentative with anyone here, but if this was not a “troll” type post and really happened, you should be ashamed of your actions instead of bragging about them and asserting you would do it again.
