As harsh as it sounds to say it, my in-laws, (MIL, in particular) convinced me that the only good in-law is a dead in-law! I did learn that once you laid down the law with them, you would get your respect...or at least be left alone. I remember having a finger-wagging, "now let me tell you one thing...." :nono conversation with my MIL. It was about her speaking of me in a negative way in front of my son (he was about 4-5), and that upset him. It was just the two of us, and you could have heard a pin drop in that room. We didn't have to revisit that subject again. I had to high-5 myself when I left her house that day! I do applaud those of you who live great distances away....smart thinking.
A good thing about her was that she loved and took good care of my son, and they had a great relationship. I didn't have to care for her to care about how my son felt about her, and respect that relationship. I'm glad he had her, and her witch daughter!
