Don't bring your manga to school!

An interesting observation about Japanese schools:

I find it funny what teachers let slide in class and what they don't. For instance, students can have loud conversations, stand up, talk back, sleep, text on cell phones, and basically completely disregard the teacher with little to no reprimand. However, if you are caught reading manga (comic books for those of you not in the know) in class, this is a serious offense! First you will be yelled at in class. Then you will be taken to the teacher's room after school and be yelled at by your homeroom teacher in front of all the other teachers. Manga is where they draw the line!

Today, in a class of 35 I counted at least 8-12 students sleeping at any given time (you can wake them up, but they just go back to sleep - plus most of the monsters were sleeping, so I let them!) and there are always a couple students texting on their phones, but the student who was caught reading manga was yelled at, called "dishonest", and later reprimanded.

I don't get it!
