How do react when well meaning relatives pry into your affairs?

As many of you know, I am a newly divorced mom. Yesterday my uncle, who also happens to be my godfather and the godfather of my youngest son, took me to lunch to, as he put it, “share some concerns” with me. He made some points about children and divorce and some observations about my children (whom he has not seen in a good four months). I was not surprised by any of these observations as I pay attention to my kids and am a very involved mother. I was offended by what he said, mostly because he seemed to think these things needed to be pointed out to me. Before I share how I reacted, I’m wondering how my fellow jellies handle situations such as these. Are you respectful with a nod and thanks for the input, or do you tell people such as these what they can do with their helpful advice.

P.S. For the record and for answerbagels who don’t know as much back story, I am a 44 year-old woman.
