You are correct! "My friend Mary" is the complete subject of the sentence. To identify the complete subject, you should look for the main noun or noun phrase that the sentence is talking about. In this case, "My friend Mary" is a noun phrase that represents the person being referred to in the sentence. It includes the possessive pronoun "My" to indicate ownership and the noun "friend Mary" to specify the person's name. Therefore, "My friend Mary" is the complete subject in this sentence.
