What were one of the meanest things your parents/parent did ?

I adopted an rescue bunny in 2016 , he had health issues , he had to be on an hay only diet for weeks , he had to have tones of mite treatmeants , I paid for all of this out of my own money. He were my bunny , I never relied on my parents. He passed away an year after. I have many stories about his antics. I became very depressed the morning I woke up for school to find him laying there dead. I cried for an whole day. I became physically ill that day. My dad just said I will take you to get another rabbit. I couldnt get out of bed. I cried that much I fell asleep. My dad agressively banged on my bedroom window constantly. After I ignored him banging on my door. Shouting and swearing. Calling me an lazy b..ch. And other names I cant say on here. It contuined for over two hours. I went to school the next day. I still dont forgive him for that.
