Cell Phone and mp3s at School

This isn't a issue in every school, but it happens to be one in mine. I for one, do not like that we are not allowed to bring cell phones and music players to school. I have a late schedule and when I get out of school, especially during winter, it is pitch black out. Plus the bus ride home and what not. I did try going to school with out my cell phone, and it was hell. When the bus didn't come and I was standing in the cold, I could of called my parents to pick me up. But of course they didn't know where I was because I had no way of calling them. I totally understand not having cell phones at school, but what about before? And after? I don't understand why we can't have cell phones and mp3 but only get it taken away if we are using it at school where it is interrupting the class. I'm pretty sure most of the teachers feel bad about the students getting their phones taken away during scanning weeks and what not. I've overheard multiple of teachers saying they feel bad they don't let students bring their phones. I've even heard a teacher saying even though her son isn't suppose to bring his phone to school she lets him just in case something happens and they need to get in contact. Aint' that some s**t? The people who are making school wide rules need to put being a parent and having their children to school instead of having unrealistic rules. That's just my opinon though. What you think?
Thats all for now:)
