I take my tama to school everyday in my purse, of course with the sound off. I only play it when i'm done with my work or the teacher isn't around my desk. In homeroom one of my friends has three tamagotchis and she never gets caught. She sits right near the teacher, too XD. Only like, two of my teachers care, luckly my reading teacher doesn't care(reading is 2 hours). My bus driver doesn't care even if we bring our DS's! XD
