Mind your Pronouns

I heard a native speaker say, “They can come with you and I.”

This is incorrect. Here, the word “I,” a subject pronoun, is used instead of the correct “me.”

Would you say, “They can come with I?”

Of course not. You’d say, “They can come with me.

I ascribe this error to an episode of the television show Bonanza where a one-room frontier schoolhouse teacher forced her barely literate charges to always use the pronoun “I.”

Me can’t think of any other explanation.
