The reason many schools do NOT allow electronic devices in school's because of theft.
You can not change the fact that your school's full of thieves. Thieves are everywhere. And when someone's electronics are stolen (usually they're expensive things like MP3 players etc) people go to to the Administration and expect them to FIND it. So instead of having to deal with the hassle, schools just say NO to electronics period.
I know this b/c I hate MANY of the rules MY own school's got. I'm a senior in High School yet I still have to follow REALLY stupid rules. Here's the MAIN idea of rules for schools. If ONE person abuses a right, ALL will loose their privilage to it.
For example, we can't have ANY drinks in ANY way in the classes. They're only allowed in the cafeteria. We can't even have WATER bottles. Why? Because someone brought alcohol to school in a water bottle, and since it was clear, no one could tell it if it wasn't water until it was too late and the child was drunk.
As far as sodas not being allowed in my school, well people are clumsy and they spill them. Then the sweetness attracts insects like ant etc etc .. Food the same reason. When you reach 12th grade (senior year in HS) you will learn in Government class that the MOMENT you set foot into that building called school, you leave behind ALL your civil rights.
You have NO rights WHAT SO EVER! So yes, I wouldn't be surprised if they don't allow tamagotchies in your school
I'm lucky they let us wear tankstops .. otherwise the weather would be unbearable! lol
