Dream with Our Eyes Open

So at the office and online, I've had examples of this common confusion whack me over the head recently:

When he accepted the transfer, Mick handed the assignment over to Fran and I.

Lyra noticed that Rock was leading the newcomer toward she and Hannah.

Look, people. If having the compound noun in the receptive (indirect object) position confuses, knock the participants back to just one, the one using a pronoun:

When he accepted the transfer, Mick handed the assignment over to I.

Lyra noticed that Rock was leading the newcomer toward she.

The problem should be glaring at this point. You shouldn't be using the nominative (subject) form of the pronouns as the indirect object. The same is true even when more than one person is involved.

So, let's rewrite our problem sentences like this:

When he accepted the transfer, Mick handed the assignment over to Fran and me.

Lyra noticed that Rock was leading the newcomer toward her and Hannah.

Thank you, folks. Really.
