Sibling Envy

Research into sibling jealousy has shown that envy often turns into rivalry as siblings get older.

As board-certified pediatrician Dan Brennan wrote for MedicineNet, examples of sibling rivalry include:

  • Name-calling
  • Telling on each other, truthfully or not
  • Ill-natured verbal "sparring"
  • Poking and hitting
  • Breaking or hiding possessions

Often, sibling rivalry and jealousy stem from parental favoritism or a low sense of self-worth and have been shown to cause health-related issues later in life including depression, according to Clinical Child and Family Psychology Review.


In the post titled "AITA for pretending not to know my sister in a class that we're both in?" the 17-year-old said he is taking a physics class over the summer to prepare for his senior year of high school.

He said his younger sister, who is going to be a junior, is also taking the class at the same school.

"It's embarrassing as hell to have my younger sister in the same advanced class as me and I genuinely hate it," the post read.

During one of the first days of class, the teen's sister approached him to ask a question to which he replied, "wait sorry who are you?"

"She laughed but I repeated it in a serious tone," the post read. "She responded with 'I'm your fu' and then I cut her off and told her that I don't help absolute randos in class."

The teen's sister laughed and shook her head but could tell he was being "dead serious" and walked away.

"I'm not lying when I say this: we haven't spoken a word to each other since that day," the post read. "At first it started with my sister ignoring me, but then I got kind of petty and started to ignore her, and well, we're in the present time now."

The teen added that their parents haven't noticed because they initiate conversations at dinner and are busy with work.

Redditor Reactions

More than 3,000 users commented on the post, many criticizing him for mistreating his younger sister.

"Ironically you are the immature one despite being the older sibling," one user commented.

"So, you ostracized her, refused to speak to her, and won't answer her question all because she's younger and goes to the same class as you?" one user commented. "Even if she's a stranger, you still shouldn't talk to her like that. YTA. Need I say more?"

"You don't get to put the blame on your sister for this petty fight and act as if you're shocked she started ignoring you after the way you treated her," one user commented, receiving more than 19,000 upvotes. "You're honestly acting like an insecure loser, and your classmates will probably think so too when they find out the game you're playing. Treat your sister better."

Other users mentioned that most of the individuals in his class are probably strangers and that his comment about not helping "randos" shows he is not a "kind person."

"Insecurities like this are going to wreck so many relationships for you," another commented.
