After making him wait while I considered my response, I explained to him that I didn't appreciate his unsolicited "coaching" of me regarding the material that post to FB and was offended by that. I also explained to him that, though we are "family," we clearly don't know enough about each other to avoid such gaffes. I suggested that, if he is interested in what is going on with me, he send me a personal message or an email. Finally, I wished him and his family well and sent him a new friend request.
I have put up with a lot of shit over the years, and a lot of being told to "tone it down" by family and others, and I'm frankly getting too old to just cave in as a matter of course. Pushing back now and then feels good.
