Student: What do we do if you die? Who do we get directions from?
Me: There will be other teachers will help you.
Same Student: But what if all the teachers in the building die?
Me: Then the principal and vice principals, and other office staff will help you.
Same Student: But what if they ALL die? How can we be officially released if every adult at school gets taken down?
Me: Dude, if every single adult on campus gets taken down, you have full permission to run away, screaming your head off.
