My sibling ratted me out. We were never really close and then one night she just shows up at my meeting (she didn't go to my hall). She said she just felt like visiting, but after the meeting I saw her in the corner talking all confidentially to 2 of my elders. It was odd, but I didn't immediately register that something was wrong, since one of the elders was an old friend of ours. I figured they were just friendly chatting. Boy was I wrong.
So the next Saturday, my wife and I are home watching college ball and suddenly we look out the window and a car with the same two elders pull up. They were supposidly just checking in on me, seeing that I was technically inactive at the time. Then at the end they started asking questions and alluding to things they "heard" concerning some alleged nefarious activity I was seen to be engaged in. I told them no and asked politely where they had heard such reports. At this time, I still hadn't put 2 and 2 together to realize that it was my dear sister. They politely refused to answer, said a prayer and wished me well. When they left it hit me like an uppercut. My own flesh and blood (whom I later confirmed was responsible, despite her denial to this day) sold me up the river for a song.
Like I mentioned earlier, we were never really close. But this was the final straw for our relationship. We still are cordial and small talk at get-togethers, but I can't ever trust or rely on her ever again. Not that I ever really had in the past.
BTW, nugget, I'll march to war at your side anytime.
