when im in school and i forget to set off my sound, i hide it in my desk and cough very loudly so noone can hear the buttons being pressed, thats also a great way to get wter without having a sore throught!
also, if you are scares of taking it to class and leaving it at home, ask to go to the bathroom, then bring your tama with you and put it in your locker, set the time to 12:00 am and it will still grow instead of pausing it all day.
trust me, i got cought by my techer, there wuz a guy in my class, i was on the slide with my friend(who lost her tama) i think they where spying on us, he saw me taking out our tamas and he said : hey, you have those yamagoocheez! (since he is pphilapeno and he dosnt know anything about tamas) then he told our teacher, she said: hand them over...
then my other teacher said... ok guys sorry, its a long story, youll be asleep by the time i finish it... mail me if you ACTUALLY want to hear the rest of the story...
