From a different thread:
My parents didn’t yell at her and then got mad at my wife and I for yelling at her.
Here’s the rule:
Take the other person out of the sentence.
Would you say, “My parents . . . got mad at I”? Of course you wouldn’t! Just because you add another person into the sentence doesn’t change you from an object to a subject. You should have said, “My parents . . . got made at my wife and me . . . .”
