To start, I'm a fifteen and a half year old girl. I've lived with my grandmother for a year due to my parents either not wanting or not being able to take care of me. My grandmother is fifty-eight. We had been out all day with my brother. When the day came to an end, my brother had needed to go to the store and my grandmother agreed to take him (he lives seperately). Me and my brother ventured into the candy aisle, because he wanted something sweet. I picked up a chocolate bar, my brother offered to buy it, but I asked my grandma instead, because my brother had already spent so much money on me today and I didn't want him spending more, even if it was just candy. She said yes. So, we checked out and got to the car. It was only until after my brother was dropped off when she asked me for some of my chocolate. I often don't mind sharing with people, I had shared my food and drink with her earlier. But, I hadn't had chocolate in a while, and didn't want to share. I told her that I didn't really want to share, and that next time we got it, I would, because I'd be feeling better. She was so fucking offended. I repeated myself, telling her that sorry, I would share next time. She got mad, saying that I was selfish and rude for not sharing. I couldn't and still can't understand how not sharing chocolate, when she had bought a whole fucking thing of doughnuts, was selfish. She went off, saying I was walking all over her, I wasn't appreciative. I told her I didn't understand how it's selfish or entitled because I would never get upset if my gift to someone wasn't shared with me, even if I had asked. I caved and gave her a piece, of which she yelled at me and said she didn't want it. I set it on the middle console of the car next to her and this bitch throws it it out the window. Now, I'm even more upset. I have a headache, I'm tired, and I'm on the verge of crying. Not even five minutes later, she says I'm selfish for not sharing because we're tight on money. As if she didn't just throw the piece I gave her out the window. I"m fed up, I don't want the damn thing anymore, so I yell at her and tell her to just throw out the whole thing or keep it for herself and I throw the half eaten chocolate in the front seat. our arguement ventured to other, unrelated topics, but I'm so pissed off and honestly embarrassed that she would yell at me because I didn't wanna share chocolate. It's not even like it was an exotic or expensive chocolate like the trending Dubai bars. It was a Lindt bar. Literally you can buy it anywhere for less than five bucks. I feel like I've lost so much trust and respect for her and I'm so conflicted and confused and I feel even more ashamed of my body. Am I The Asshole? (Sorry for any mistakes, I'm in the dark and can't really read off the computer too well </3)
