My mom always threatens my sister with physical violence, but she never actually hits her. Though sometimes she raises her hand like she's going to, and when my sister flinches, my mom puts her hands down. Lately it's been getting worse. She's still not hitting her, but she gets right in her face and just screams at her and insults her until she breaks down crying over innocent little accidents. I'm just worried that this will escalate. My mom was never like this with me.
