if just drawing a gun would get you suspended I can't imagine what would have happened to me.
I used to doodle battlecruisers complete with weapon systems, decks, bridges, etc. lol.
I used to doodle weapons and try to figure out how the action would work, and how that could combine with the the ergonomics to create a realy "cool" automatic rifle - or design the combat knife I'd like to own. Did plenty of battle cruisers, too.
Along with those, I doodled B-17s, P-51s, P-47s, F4Fs, Sherman tanks, PkwIVs, pirate ships, giant robots, powered armor (after I read Starship Troopers, my GI Joe in the Mercury Spacesuit, became a Mobile Infantryman, using an M-60 with its barrel broken off as a flamer, and the Life Support pack as the jump pack/ Y rack), etc.
No way could I ever survive zero tolerance.
I came home from work one day to see my son with a weird Tinkertoy apparatus around his head. He made a Halo, just like a friend with a broken neck was wearing. The difference was that my son's halo was mounted with several guns. Cause that's how boys think and that's what boys do.
