I left school 4 years ago so no i don't, but back in the days of Red, Blue and Yellow, and later Gold Silver and Crystal, i always had my Game Boy with me in School, but at that time EVERYONE had a Game Boy and Pokémon with them in school, in fact it got so bad in my school that they didn't have the power to confiscate them all so instead the teachers actually set up break time tournaments for us and gave out prizes (usually just points to which of the 4 school houses you where in, but we where all very competitive about that so it was a good prize) but you where disqualified if you where caught playing in class, it was fun too i remember winning quite a few times, but when we moved up to high school most people just stopped playing Pokémon, i too stopped too but when Ruby and Sapphire came out i decided to give in and start playing again, none of my friends found out but i wouldn't have cared if they had, but now I'm in collage i would never take a DS or anything in with me (at least not to play in class) my lesions are too important to me and beside 90% are practical anyway so there would be no time to play games, but i do sometimes take it on the Bus/Train with me to play.
