My interests can basically be summed up as "fictional characters" and "cats".
On fictional characters:
I have been interested in various fictional characters ever since I was a toddler. The characters I'm interested in are highly subject to change, but my interest in the topic of fictional characters in general does not. (I hope that makes sense?)
One thing I'm really into is shipping (pairing off two characters romantically). I especially like to create my own pairings that I haven't seen anyone else ship before. I'm especially into crossover pairings for this reason. Sometimes I like to create lists of my favorite crossover pairings, organized by type (het, slash and femslash) and series.
On cats:
Cats have always been a major part of my life. My earliest memory involves being driven to the animal shelter to pick out my first cat. Ever since then, I have never been without a cat. And as a result of wanting to be a good cat owner, I have studied cats and their behavior extensively. I also enjoy learning cat facts such as "who was the longest-living cat", "who was the smallest cat", etc.
I've tried really hard to get into other subjects that are more "useful" or "intelligent", like computer code or astronomy, but I find these other subjects to be incredibly boring and they never hold my interest for more than a few minutes. I've even tried "personifying" concepts and objects into characters - which, believe it or not, is actually a popular trend among otaku. You'd think this would work for me, but it really doesn't, haha. I'm just glad I'm not in school anymore; I probably wouldn't ever be able to focus!
