Theres this girl about 9, just turned 9. A family friend (well her and her mum). At the start of the year she started getting into pokemon (her mum got another boyfriend with two sons, I think that's where it started). First she was obsessed with piplup and I was a tad worried that she wouldn't know about the original pokemon. That is until I had to babysit her for a night and we watched the original pokemon shows in kanto all night, that I remembered watching like 10 years ago. And then she got obsessed with bulbasaur. And then I gave her these cards (not tcg ones, just pretty ones) with kanto pokemon on them, printed at least before 2000 that i didn't want anymore. She knew like almost every pokemon on them, got excited about the charizard one and thought it was the best. And I know heartgold is a newer game still, but it's still the jhoto region, and I thought it was cool when she got excited about me letting her borrow it.
It's just good that she knows all the old pokemon, a lot of kids her ages wouldn't have a clue.
