I and Me

"I" and "Me" are both pronouns related to oneself but serve different grammatical roles. "I" is a subject pronoun, meaning it is used when the person is performing the action of the sentence (e.g., "I am going to the store"). "Me" is an object pronoun, used when the person is receiving the action or is the object of a preposition (e.g., "The teacher called me," or "She sat next to me"). Their proper use depends on whether the pronoun is the doer or receiver of the action in a sentence.
