More family weirdness

So today my sister-in-law told me that my niece(not her daughter) had seen my profile picture on Facebook and asked her parents why I had my friend(actually it's Kip) in my picture with me. Her parents said they didn't know. Anyways, I found out that my niece is no longer friends with me...so, I believe her parents have access to her account and deleted me as her friend because she was asking questions about me and Kip. If it's true that her parents defriended us, it's just sad that my only contact with my niece has now been severed. Did I mention my niece is 14? My sister-in-law also said that my brother(to clarify, not her husband) told her he needed to start having a relationship with me and have a talk with his family. Maybe this defriending is only temporary until he tells his daughter. Who knows?
