Is AUTHOR wrong in the post ? POST : My dad is out of town on a business trip and I was staying at my moms. I needed to get something from the house though so I texted my dad and told him I was coming over to get my stuff. He didn’t respond (later learned was on a flight) but I thought nobody was home so I went in. My stepmom was on the couch watching tv and it looked like i scared her walking in through the front door. She told me firmly that I can’t enter the house without permission and If i do it again they will change the code to the front door (It is a electronic door that uses a key pad to enter). My dad calls me later and says because I don’t have a relationship with my stepmom I cannot enter at my own will. We argue and don’t get anywhere for 15 minutes. I don’t think it’s a privilege to enter my own house without asking, in this case with no response to my request, but apparently it’s a privilege to step in one at all according to them. 
Little backstory its my dads gf but easier to call it stepmom and I can’t be home alone with friends over, even if stepmom is home (because i don’t have a relationship with her), and also I don’t have access to my garage code. 

AITA?
