I felt annoyed

Hi, I have finnished my secondary school about 3 month ago. I have a younger brother which he's on primary school but he don't like school anymore. Sometimes he make an excuse to my parent so he didn't go to school. About this 3 month of time, I saw that he make an excuse frequently to my parents because he don't want to go to school. Whats annoyed me is my parents just believed what he say and gave him a permission to rest at home. He always say that he tired or headache but thats just his trick to not go to school. He also always complained why I can stay at home while he should go to school. Sometimes he tell the things that are not true to his friend at school such as I'm at home slept a lot and didn't help my parent but the truth is I'm at home always helped my mother do all the house works and don't got a chance to sleep because I have a lot of work to do. He just got jealous of me because I can stayed at home and didn't have to go to school.
