Cold and angry

My dad is currently letting all the heat out of our house and into the garage so he can lift weights in there. 🙄 It is literally so cold in the house. Its 40 degrees outside, and idk what it is in here. I have on a long sleeved shirt, long pants, socks and I’m under a blanket and I’m still cold. He won’t listen to reason. He just gets super angry. My mom told him that she would like to start cooking dinner soon, but the kitchen is right next to the garage and it’s too cold. He yelled at her “well the fucking garage has to heat up!” Im just done with how selfish he is. He doesn’t care at all how cold we are, and I especially have problems with the way he talks to my mom. He doesn’t even think about what she’s saying, he just reacts like a volcano of hatred. I wish I could move out, but I’m still paying off student debt...
