I always bring my Tamagotchi to school. I never have to worry about turning the sound off, 'cause I always feed it heaps and play with it heaps during recess. My lessons are only 50 minutes, and there are two lessons between each recess, so that's 100 minutes - an hour and 40 minutes. It's not long at all.
I tested my Tamagotchi yesterday; instead of playing with it 24hrs a day, I actually left it. I'd played with it so much the day before and fed it and everything before it went to bed. It was five hours before one hunger heart went down! At the moment, my Tamagotchi is an adult, and it's training points are at full; so it won't beep at me for no reason. I let it be itself, I never pause it or turn the sound off during class, I just play with it at recess.
I'm doing end of year exams at the moment. But I needn't turn the sound off or put it on pause, 'cause it's such a patient little thing, it knows I'll play with it later when I'm finished. I love my Tamagotchi.
And guess what, I'm a nerd too! I play with my Tamagotchi as if it's a real, living thing! I love it to bits! You should
see the topic I made about how cute Teletchi is, and how sweet it is to see Teletchi walking along with its parent before the parent leaves their Teletchi to me. I really love my Tamagotchi, as though it's my own son/daughter, it's my best friend at the moment 'cause I'm having troubles with my real friends. I'm really attached to my Tamagotchi, now more than ever before.
So don't diss people who love their Tamagotchies! That's why they're on TamaTalk - 'cause they love their Tamas! Am I right, Tama-lovers?
Sorry for rambling.
