Our dad is in the process of kicking out our oldest sister because of money
English isn’t my first language so I apologize for any mistakes in advance.
Today my (18 y/o) sister (23 y/o, whom I’ll call Susan) was told by oldest sister (40 y/o, Lizzie) that our mom (60s) wanted her gold jewelry back to sell it for extra money so mom would be able to travel (I think my mom gifted to her). Lizzie was obviously upset over this and told her no. My mom said some mean things to her and closed the door in her face. Now, my dad (60s) is a very furious man and he’d do anything for my mom. He goes and threatens to take Lizzie to court if she doesn’t give it back. Lizzie tells him that she sold it for 9-12k. He tells her to pay mom back but that’s a large sum of money and Lizzie has been looking for an excuse to move out (it’s looked down upon in our society to move out as woman if you aren’t married yet, and will likely affect you). My dad, mom, and oldest brother (30s) left to go have lunch. My other brother (30 y/o) genuinely doesn’t care. Susan and I have no clue what to do. We know that Lizzie will be able to support herself financially but this situation is shit and we don’t know how to support her, and she didn’t want our help and she’s not telling us where she’s going. I’m honestly really pissed off and unwell right now so this might not make sense.
Thank you for reading, any advice would be appreciated.
