Question

Which is correct, I or me? Lydia and I/me are going to be in the play.

Answer 1

Me is an object pronoun. I is a first person singular pronoun, meaning that it refers to the person performing the action of a verb. Does that help?

Answer 2

"Lydia and I are going to be in the play" is the best answer. Whenever you refer to yourself with someone, you always use I, I would think.
