I moved into my parent again, in my little town in Norway due to economic reasons I have. My mother are ok sometimes.my father has always been a asshole to my mother and his children. The local mosque (mostly just oromos that goes) has started to Harassed my little sister, she just is 13 years old she doesn’t wear hijab bc she doesn’t want it. My parents don’t care. But the Oromos call her a for not wear it, and names that kills her self esteem. Some girls stared to beat her up bc she doesn’t wear the hijab and wear western jeans. What should I do as a big sister?
