'me' is considered to be a personal pronoun and reflects the first-person singular point of view. As such, it typically takes on the role of the subject of the sentence.
1. 'Me and my friends decided to go to the beach.'
2. 'I helped me with my homework.'
3. 'He asked me to send him a postcard.'
it is important to note that personal pronouns like 'me' can be used in place of the subject of the sentence, but can only be used in the first person. Additionally, when 'me' is used as the subject of a sentence, it should always be preceded by the pronoun 'I.'
