“My Friend and I”

You have just poked yourself in the eye with a pencil, and your mother is screaming at you, “What are you trying to do to your father and I.” Then you say, “Mom, that should be ‘your father and me’.” And then she gets REALLY mad. But you are right.

Pronouns that are object of a preposition or a verb take the objective case: me, you, him, her, us, them.

The horse is under me.

Pronouns that are the subject of a sentence or the complement after a linking verb take the nomnative or subjective case: I, you, he, she, we, they.

I am the king.

It is I, the king.

The chart below shows the breakdown.

Pronouns still follow these rules when they are paired with another noun: my girlfriend and I, your father and me, our parents and us, and so on.

So this sentence

The dog bit me.

and this sentence

The dog bit your father and me.

are both using correct pronoun case.

The man gave a million dollars to me.

and

The man gave a million dollars to your father and me.

are both correct.
