When my older daughter was in kindergarten or first grade, she had one of those handheld digital pet devices like the Tamagotchi, although I don't think it was Tamagotchi, maybe some other brand. Perhaps the Giga or Nano brand. Anyhow...
Her digital pet was a little puppy whose needs had to be met, so it can grow bigger. It had to be fed, bathed, exercised, disciplined, toilet trained and nursed back to health when it got sick. And if you didn't care for it properly, it would get sick and die. This could happen in less than half a day, so you really had to be on the ball.
This was quite a lot of responsibility but my daughter, a child that took responsibility very seriously, did a great job. The puppy was happy, it thrived and grew steadily into a larger dog. And since the kids weren't allowed to take these toys to school (for obvious reasons), my daughter entrusted that little 'pet' to me. While she was in the classroom, I looked after it. And did a good job. Until the day that I forgot about it completely and saw the message "goodbye" flashing on the screen, which indicated that the 'pet' had died.
So what did I do? I wimped out and lied. I started the game over and told my daughter when she got home from school that her dog had grown up and had babies of its own and now we had a new puppy to take care of. I held my breath and waited for her reaction. She stared at me for the longest time as she analyzed the story in her six-year-old mind...and finally nodded. A new puppy would be fun. I'd gotten away with it but I felt really guilty. Over a virtual flippin' pet! Years later, I confessed to my daughter what really happened and we both had a good laugh over it. All was forgiven!
Do you remember these toys?
