Hi everybody. I don’t know if admin will allow this post, if not feel free to delete. I don’t know what to do. My sister has threatened to punch our 82 yo mom on several occasions in abusive phone calls. My sister is losing the plot big time. She says ‘ if you were in front of me now I’d hit you’. My mom is getting desperately worn down. She’s promised me to secrecy. I’ve promised her I won’t say as long as she keeps talking to me about what’s happening. I’m so worried if I confront my sister it will escalate very quickly and possibly go underground. My mom loves my sister but it’s getting to much and I don’t know what to do for the best. If it was anyone else threatening my mom I’d get the bat out, no problem. I’d do bird for it, no problem. I’m completely stuck. It’s anonymous on her and I value your opinions. All you guys feel like true friends so I’m asking for your help. I don’t know what to do for the best.
