Here are the facts:
I don't use facebook much.
My thirty something nephew sent me a friend request shortly after I opened my facebook account. I accepted the request. I received lots of things from nephew on my wall, photos, jokes, links, observations. I "liked" some and commented on some. I presume these items were sent out to lots of nephew's friends, not just to me.
A few months ago, all messages from nephew stopped. I visited his wall and noticed that nothing new was being posted there. He has put a couple of things up on his wall in the past few days. I tried to "like" one of them repeatedly but it doesn't work. The "like" count goes up by one but then it goes back down and my picture doesn't show up in the like list.
It appears to me that my nephew has blocked me, doesn't it? Now, I can understand that there are things he might want to post that he doesn't want his aging aunt to see but ... everything? I can't understand why he would send me a friend request and then block me later on when I have done nothing, and I mean nothing, to offend him and it is not that I have suddenly become the aging aunt. I've always been the aging aunt.
My nephew has always been unfailingly polite and friendly to me. We do not see each other often because of distance but are always friendly when we do see each other.
Now, the etiquette question:
DH and I will be seeing nephew at Thanksgiving, along with several other members of his immediate family. Should I ask him about this or just not mention it?
