If you wanted to teach your kid responsibility, but you were pretty sure they were going to fail in learning all that much, it was time for a Tamogatchi. The former hot Christmas toy was the first way that many children learned about death.

Though for most of us, it takes until we finish college to start grappling with how harsh life can be, for an entire generation, these hard lessons began with Tamogatchi.
