Is OTHER wrong in the post ? POST : (Obligatory apology for being on mobile and that it’s late for me so my grammar might suck)
My stepsister is 4f, I am 13f. I also have high functioning autism (this is important I swear) 
I absolutely ***hate*** little kids. My stepdad acts as if I’m obligated to like his daughter for no good reason. She isn’t cute. She isn’t funny, and everything she makes is ugly. Now I’m really making this sound as if I’m the ass, I’m trying not to be so let me explain. She will run into my already cramped room (me + my other stepsister(8f)  + a rabbit, in a 8x11 foot room) and just sit and watch me. She also tries to hug me, even though I don’t like being hugged due to my Aspergers. My stepdad brushes this off and makes me hug her. He also doesn’t discipline her when she runs around naked in the middle of getting changed or having a bath. 
What’s worse is that he expects me to obey him like they do which has really made me resent her. He has attempted to force me to eat foods I cannot eat (I have sensory processing disorder along with autism, and I have a really hard time with food, for example, tasting a seed in my mashed potatoes will make me gag) 
(TLDR Aita for making my stepdad angry via not liking his kid and him misunderstanding my autism?)
