Posted for my friend who doesn’t have a Reddit account

I, (15F) have a sister who we will call B (14F). A couple of weeks ago she told me one of her friends in school was selling mangas (Haikyuu for anyone who’s interested) for incredibly cheap, about 15$ US for 2 books.

My sister has owed me money all the way from 2023. I’m the type of person that keeps track of money people owe me, which sounds petty, but I always pay for people when they don’t have the cash in the moment and offer to pay later, and I take those promises very seriously.

My sister kept promising to pay me back for some small transactions (chips, candy, the usual) and still, to this day, has not paid me back. I’m not frustrated over the amount of money that she owes, which is really not a lot, but I’m getting mad about the fact that she’s promising to pay and still is not.

So last night, my sister came up to me and told me her friend wanted the money the next day, and I had this brilliant idea that she will pay all the money she was in debt to me and I will pay the rest (it’s about 13$ US). She said no. All the frustration from the years built up in that moment and we start going back and forth with classic sibling insults. As I mentioned before, I take promises seriously . Breaking promises are is biggest betrayal for me, even if it’s something so small. My sister had promised me multiple times and yet never fulfilled it.

After we continued disagreeing with each other, she said “whatever,” and went upstairs. I was so mad to the point I felt like crying, even though I wasn’t sad, I felt so many emotions like feeling worthless. Btw my parents were there the entire time and said nothing until my sister left.

My parents asked me what was that about, and the flood gates were open, so I started crying.

I told them everything: the promises, how long I have been waiting. I know it’s quite petty to be so frustrated about a couple bucks, but nevermind. My mum went upstairs to go to my sister. Then, I was saying empty threats like if she doesn’t pay me back tonight, I will make her pay double.

Now this is where I become the asshole as during my rant to my parents then to only my dad, who wasn’t even listening to me, I started texting my sister.

ME: You’re the worst B: Piss off ME: U piss off Ur legit the worst person I have ever met If u don’t pay now like mum says I will make u pay double i don’t fucking care Times like this I understand why (name) hates you I completely understand

(For some context, name is an ex-friend of my sisters who she has a huge history with)

A few seconds later I hear the door opening and my mum yelled out “What the fuck did you write!?” And I could hear my sister crying (which is shocking since our house is 3 floors and my sister’s bedroom is the only room at the third floor).

My dad, who btw doesn’t know what I wrote at this time, immediately stood up and became defensive for my sister. I don’t remember what he exactly said but I remember at the end he said if I do this again he is going to ‘get me’ (meaning he was going to hit me). He told me to go to my room and how he was going to take my devices. I left my phone with him and went to my room.

Not even a minute later, my dad comes in my room and had my sister’s phone with him and he was showing me to messages and kept asking what is wrong with me. Like I know what I wrote, thanks dad.

After he threatens me again, he leaves and comes back with money and throws it on my table and said that I got what I want. He also told me I better apologize to my sister.

So am I the asshole? This is quite normal for me, every time I complain about my sister, I end up getting in trouble either by how I reacted to what she did (like what happened last night) or she will bring up something petty, that happened months ago, only because it’s convenient for her.
