I’ll go first: I once had a weird hyperfixation on leopards and jaguars (cheetahs are cool too, but not gonna lie, I didn’t care that much about them). I don’t know what got into me, but I wanted to learn how to tell them apart, pick up a few facts about them, and I even took a few quizzes to check if I could differentiate them (thankfully, I got everything right—because if I hadn’t, I would’ve felt like a failure). Anyway, I’ve definitely had more, but this was one of them.
