Blocked my youngest sister on messaging me. She’s just constantly rude. She literally said can you have respect and stop rubbing or hitting against the wall. Like my bed is against the wall. My daughter was leaning against it. Her kid sits there for 30 minutes at 11 At night banging her head at her wall. I don’t say anything cause she is around my kids age. But I expected the same respect and understanding. I am looking to leave now cause I’m so agitated lately and it’s getting worse with how much stress im under here.
