They stayed for an hour and at the end asked her to tell me that I should still limit my contact with my mother since I am not attending meetings etc.
I thought it was strange until she told me the name of the Elders, both on my JC and both still it seeems bitter!
Are you DFd/DAd? If so, I think I'd be tempted to call on them and let them know that sis actually did deliver their message. And my message in return? Mind your own fucking business. Don't pretend to think you can tell me, or even suggest to me, who I can contact, how much, where, when or how.
But if you're inactive, staying under the radar, refusing to meet up with them, that strategy would not be recommended.
