We are 3 kids in my family:my older sister who is 2 years older than me and my younger brother. Two days ago, when I was preparing for my exams,suddenly she came and started arguing about tiny things that means almost nothing such as using her pan and pencil ,like is she begrudging it from me?? This thing is not that expensive or it's not rare thing so it's complaint to find or purchase. I was really mad at her that time and from my own perspective, it's disgusting from her side to begrudge something from me.
