Is AUTHOR wrong in the post ? POST : My sister had just come back from hanging out with her friend and brought back her leftovers from McDonalds where they ate. She finished her leftovers at the dinner table and left behind her trash all over the table while she went to lay down on her bed and use her phone. I cleaned up the table because she really did make a huge mess. I throw out all the garbage (which means that I took it outside to the dumpster). 

About an hour later I see her looking in the trash and I ask her what she's looking for. She says that she is looking for her phone charger and all I say is that I don't know where it is. She then asks me if I threw out everything that was on the table (which should have been obvious since the table was cleared of her mess) to which I respond with a simple yes. She then begins to yell at me and berate me because she left her charger in her McDonalds bag. I apologize, but I also tell her that she shouldn't have left something as important as a phone charger in her trash. She keeps screaming at me and continues to berate me. She also demands me to go outside, reach into the dumpster and grab the trash bag, bring it upstairs so she can look for the charger, all during a snowstorm that had just started. I tell her that she must be crazy if she thinks that i'm going out there in the cold and rummage through the dumpster and that she should go look for it herself if she wants it so badly. She gets more mad and punches me as she goes to her room. 

The next morning she goes outside to look for it, but the garbage truck had already come and collected the trash. She wakes me up by screaming, punching me, and demanding me to buy her a nee charger. I push her off of me and tell her to buy it herself and to not be so careless with her stuff.

My Dad is telling me that I should buy her the charger since it was ny fault, but my mom is telling me the opposite.

Am I truly the asshole in this situation?
