I tolerate mine. Over the last 30 years (4 years dating, 26 years married) it's been bumpy to say the least. MIL is a control freak so she naturally will clash with my strong, independent, assertive personality.
She goes in and out of Church Lady Church Chat persona, so she's difficult to tolerate.
Things are pleasant and civil, but she knows not to over step. She's currently picking on one of the other daughters-in-law, so right now, I'm out of the hot seat. There are three of us, and she has her favorite. 4951
