Even when they "mark their bodies like the heathens" and/or get assorted metal objects inserted into their anatomies.

Even when they work all the time and live in a small apartment, but get a Great Dane puppy anyway, then don't have time to train it properly. (We are not, however, required to do it for them, or to dog sit.)

Even when they decide to go to the other in-laws' for Christmas. (Choke. Sob.)

The exception that proves the rule: The one time this rule doesn't apply is when there might be abuse involved. A Magnificent MIL never turns a blind eye to evidence that indicates abuse, even if it points to her own child.

If a MIL has good reason to suspect this serious problem in any form, she won't share her suspicions with anybody until she's consulted with a local shelter or agency to get solid information about the best course of action.

Tempting though it may be if the SIL is suspected of abuse, Magnificent MILs do not take the law into their own hands.

If any man ever beat my daughter, I'd want to grab my granddaddy's shotgun and do some rough justice, then and there. Wanting to do that is normal. Doing it isn't.

This is America, and people are innocent till convicted by a court of law, even if we catch them in the act.

That doesn't stop Magnificent MILs from creative problem solving. I know of a MIL who responded to her abused daughter's frantic call for help by calling 9-1-1, only to be told the police would be thirty minutes getting to her daughter's house. Frantic, she raced over there to find her child bruised and bleeding, and the drunk, abusive husband passed out on the kitchen floor, stark naked except for a dish towel placed over his privates by her daughter.

Lacking any rope to tie him with, this enterprising MIL drizzled most of a six-pack of instant glue onto the seat and back of a sturdy wooden kitchen chair. With her daughter's help, she hoisted the louse into the chair, covered his privates with the lightly glued dishtowel, then held him tightly against the chair till the glue set up. Just to make sure he couldn't do any further damage before the police got there, she pulled his hands behind the back of the chair and neatly glued his palms and fingers together as if in prayer, but aimed in a direction more appropriate to his bad behavior.

To spare the terrified children from seeing their father that way, she gagged him loosely with a pair of Sunset Tan pantyhose, then draped a clean king-sized sheet over him, thereby earning the Betty Crocker Seal of Approval.

She then tended to her daughter and helped pack up the children and belongings.

Personally, I call that just plain elegant, proof that the crassest of components can make up a deliciously delicate whole. From what I hear, the police, who didn't get there till an hour after her call, thought so, too.

The only trouble was, the chair wouldn't fit into the squad car, so they had to send for a paddy wagon.

The arraignment in Cobb County night court is now a legend.
