She never forgot when it was something for her own convenience. It was pure selfishness. If I asked her to not eat a dessert, as it was a birthday gift from my mom, sealed it in a tied bag, and wrote on it "for Erin," and verbally confirmed with her that it was mine and I did not want her to eat it, she would then decide later that day while I was at work that she was hungry and eat it anyways. "I'm sorry, I forgot, and I was so hungry." It was sealed and tied in a bag with my name on it. You told me that you wouldn't eat it, and that it was a birthday gift for me. She was like this for every aspect of our relationship. If it affects me, conveniently forget. If it is for her, perfect memory.
