Is AUTHOR wrong in the post ? POST : My stepmom likes to buy stuff for me to try and get me to like her. She started dating my dad last year a few months after him and my mom split and they got married a couple of months ago. I dont particularly like her and she knows it so she tries to buy me stuff to make me like her. I’ve told my dad to tell her to stop buying me stuff but he said she likes getting stuff for me and I should be grateful. 

Im thinking about selling the stuff she bought me on eBay. I could do with the money and maybe they’ll get the picture. AITA if I do this?
