Does seem a little extreame. Although at my school the worst thing is pda (public display of efection) while they know it's natural. If I was a teacher i'd be woried if it didn't happen. most is 5 days in iss/oss.

Only time in our school we get suspended is if you get in a fight or steal someone else's coursework and claim it as your own. If you point a rubber band at someone that rubberband will just be taken off you.

as far as i know we dont even have rules against rubber band flicking. if people are shooting them all over the place the teacher might yell at you but normally nothing would happen. i remember once I flicked a pen inside ( by turning it over and using the spring to propel it) and it flew across the room and hit our teacher on the back. i was horrified but the teacher just laughed and threw it back to me. so yes i think thats REALLY extreme.
