i hate when people fake their intresets

I have this one "friend" and she is SO annoying. She posted a lipsync to one of my old fav songs "beachboy" by Mccafferty and naturally i asked her "whats your fav mccafferty song??" and she said "i dont listen to them" so i was like whatever in my mind right. Then at school she started junko posing and as someone who is PASSIONATE about danganronpa i asked her "whos ur fav ultimate" and she said "whats that?" and i said "danganronpa character, i like kokichi and nagito"  then she said "i havent watched it" so i was kinda ticked but whatever right. Then she started talking and reposting about MHA so i asked her "what season are you on? or did you finish it?" and guess what she said.."i havent watched it..but in 2020 i was like there for it yknow" NO I DONT FUCKING KNOW. I also asked the friendgroup about their playlists and their fav songs and i use deezer so i have one playlist for everything, and i saw her playlists and it was her "favorite songs" and her songs that she "actually listens to"..all the songs on her favs but not the ones she listens to were from NIRVANA and the other ones were from other artists. if you like the songs shouldnt you also listen to them??? like tf?? she also reposts stuff about being alternative an shit but she doesnt know ANYTHING about politics other than "trump is bad" WHICH SHE GOT FROM FUCKING TIKTOK </3 Im gonna be honest i posered in fandoms before but i dont anymore because i get how annoying it is for real fans
