I think one of the greatest joys of fandom is being able to look back on a certain media or a ship or a trope or event or something of that nature, and being able to remember like "oh yeah! that was how I became friends with [x]!" "that was when that friend and I watched that show and stayed up until 2 am to do it!" and when those friendships bleed back over to real life too, like "oh I tried that food bc x says they like it!" and "that's x's favorite animal!" and all these sorts of things that happened because we happened to meet just like, in the great vastness of 1) human existence and 2) the ephemerality of fandom existence.
The way that certain things become suffused with that friendship and the like joy that really is. What an uncommon occurrence. What a lovely thing it is. What an honor. What a privilege.
I met my best friend of 21 years (and counting) because some Little Shit insulted me over the contents of some fanart I did (Little Shit was all "he's mine" over a fictional character she didn't create just because SHE wanted to be the only one allowed to imagine she was dating him when the fanart wasn't even shippy. It was more along the lines of two friends annoying each other). When I clapped back and read her for filth while insulting her Self-Insert Mary Sue fanfic with her Wildly OOC take on the guy she was trying to claim was hers (I was very "eye for an eye" back then and I forced myself to read it just to insult it/her) and her traced "fanart" she went crying to the chick who would become my bestie. Literally.
Bestie DMed me to tell me I made Little Shit cry and that I was her new favorite person (she hated Little Shit, too, and Little Shit didn't get the memo). Then we proceeded to nerd about the fandom and never stopped talking.
Friends for 21 years. Living together for 10. This bitch is my ride-or-die just because some Little Shit got her panties in a twist over the protagonist of an obscure anime movie/series of novels potentially loving anyone who wasn't her/her Mary Sue.
Fandom is weird, man.
