Story about the first time i hyperfixated on something really bad as a child

So, when i was little, and i mean like maybe 10-ish, my grandparents lived with my Poppa's parents out in the wilderness of Tennessee. like, 30 minutes from this itty-bitty town and 2 hours from Nashville, right? well their farmhouse has a loft where my parents got to stay whenever we went down to visit them, right? well one time i asked to use my Grammie's phone to watch dinosaur videos, which i was really into from a young age, and then disappeared up into the loft. i watched maybe 2 fact videos before another extinct animal video showed up. Now, I've always been into animal facts and history and especially extinct animals, so this was right up my alley. i clicked, i watched, and something caught my attention.

Tasmanian Tigers, aka Thylacines.

I hyperfixated SO HARD i was upstairs in that loft for a good 5-7 hours just watching thylacine videos about the last one (WHO WAS NOT NAMED BENJAMIN, BTW.) and looking for them and documentaries and scientific efforts to revive them. I don't think anybody even knew i was up there until Grammie wanted her phone back because dinner was ready. I got called down and marched down those stairs like i owned the mother fucking world. my hair was a fucking mess, my eyes were red from rubbing them, i was a lil dehydrated and starving, i really had to use the bathroom and i just started word vomiting thylacine facts like a mad man. I genuinely believe my family thought I was crazy. this process repeated for i believe the rest of that trip.

Well, anyways, i told my Mom about some recent thylacine news tonight and mentioned my disappearances that caused my interest, and she looked at me like i was insane. apparently nobody realized i was up there i was so quiet (and it was a good few acres they lived on so i could've been anywhere) and yeah. my first (that i remember) hyperfixation experience as an unknown and undiagnosed autistic child.
