this is how you train your tamagotchi:
when your tamagotchi is crying, you have to praise it. when it has its back turned against you, that means it is mad and you need to praise it.
when your tamagotchi beeps and calls you for no reason whatsoever, you need to give it a timeout.
if you have the sound off, you can still know if it needs training by looking at the attention icon, the icon at the bottom right corner.if it is lit up, your tamagotchi needs something, food or needs playing with or needs training.

PS, the more training bar you have, the better.
