So, totally only semi-related:
A few weeks ago, my 6 year old shows up on daddy day carrying a huge binder filled with Pokemon cards. It is a nice binder, made to look like a Pokeball. It has a fabric elastic strap that keeps it closed. This is an obvious hand-me-down from one of the people who works with his mom at his school.
I learned how to play the card game. I read him all the text on the cards (he's OK with reading, his confidence just isn't there yet). He's got some good ones, too! A couple of fairly rare foils (yes, I looked them up).
Today, I went with my mom to Target, for a "completely unrelated reason." The main, real, reason I insisted on joining her: I bought $80 worth of Pokemon cards, sleeves, and some album sleeves.
I just thought, "OK, fine. If he's into it, I should be there, too."
I am currently sorting and sleeving, or sticking them in the album sleeves, by type. I have never sleeved cards in my life, and I was into MtG the year it came out! I've worked in the toy industry off and on since the 90's, and I've never owned anything Pokemon, except for GO! and Stadium (but even that was more my older son's).
What. Just, what.
I suppose if my teenager can get me into MLP: FiM, I can get behind my little guy's Pokemon thing. Even if it cost me eighty bucks, that's not a big deal in the scale of tabletop games.
Edit: my older kid helped me to sort and sleeve these cards. Extra bonus bonding time!
