A genuine question

Can I beat up my sister?

She hid my earbuds and only gave them back after 4 days then told me "YoU sHoUlD bE gRaTeFuL I eVeN gAvE tHeM bAcK tO yOu!"

Mf literally stole my stuff and expect me to be grateful. I knew she did this before, stealing my things but the fact she tells me to be grateful makes me wanna throw her make up tools in her face and tell her that " YOU SHOULD BE GRATEFUL I MADE YOU PRETTY BITCH"
