Pokemon was actually kinda the only point of contact I had with my classmates in elementary school! I guess my tastes were kinda niche. Almost any good memories I have from that time are related to Pokemon in some way, especially the cards.
I didn't have many actual friends before that (and was bullied..) and I was obsessed with the anime, until one day I saw some classmates playing with the cards, and was immediately invested. One of them let me keep a common Eevee card he had doubles of (my favorite pokemon at the time) and I took it home and legit spent the whole day looking at it. It went downhill from there XD Btw, this was in grade 2, and I avidly collected pokemon cards until grade 7.
Once we tried to organize a tcg tournament by ourselves, but we didn't have enough break time to get past round 1, and you can guess how well a bunch of 7 year olds could keep track of a game to finish the next day. It made me so frustrated, because I had really put in the effort when deckbuilding for the tournament...! I also vividly remember getting scammed by an older kid and trading a cool ass holographic Rayquaza for a mildly rare Gardevoir. Still bitter about it :')
Ah, and one day we decided our class should have a tcg "guild". Doesn't mean anything, we just wanted a cool name for our group of tcg players. I got to draw the emblem! I was the only art kid in the group. I think it was an Umbreon? Wish I still had it.
I also had my most anime moment when I saw some kids in the playground ruining a Magikarp card just because it sucked, and I felt like I had to say something because the anime taught us to not beat pokemon (yeah I was like that) so I asked them to stop and kept the card. The same day I got a booster pack, and found a Gyarados in it. I was overjoyed lol. I knew how silly I sounded even back then, but it still didn't keep me from yapping about it.
Wow, I rambled a lot there... I just have so many little anecdotes like these from school, really makes me realize how I wouldn't be who I am today without Pokemon. It has been a part of my life for as long as I can remember, goddamnit. I love reading stuff like this from others, nice thread idea!!
