Is it normal that i'm easily annoyed my my younger sister?
I have a sometimes irrational tendency to get annoyed at my sister. It always backfires on me, however, with me constantly grounded or scolded on each and every occasion.
Example:
Tonight at dinner, she kept repeating "eeetzzzz naaaattttinnng" in a drawn-out, obnoxious way. It got so bad that I was grinding my teeth and clenching my fists while I watched her teach this phrase to my younger cousins who then proceeded to repeat this phrase to my face while grinning at the expression of annoyance and resignation on my face.
I walked out on dinner, then had to listen to the sounds of their laughter at my sister's *roll's eyes* hilarious stories.
Of course, I was blamed for being hot-headed and was scolded for a good hour while having to endure my sister smirking behind my parents' back.
Not a day goes by that I'm not tormented like this. All I want to know is: Am I normal for being annoyed at these kind of situations or were my parents right in calling me a 'hot-headed idiot who needs to learn to calm down and not "freak out" at such trivial things'?
