Me and my friend OR My friend and I

The thing here, is that this is the one grammar point every native speaker has been taught to hear as wrong. Everyone in school had a teacher who would say "MIKE and I" emphatically if "Mike and me" or "Me and Mike" was said in conversation. GRAMMATICALLY SPEAKING is it wrong? Depends who you ask. Take for example this question: "Who is hungry?" ANSWER: ME. Did everyone hear that, I asked who is hungry? Who is hungry here? : ANSWER: MY FRIEND. However, we have all been taught to say MY FRIEND AND I so much, that people inherently think it is wrong. EVEN with Judy's example of a prepositional phrase He bought gifts for my friend and me, I still hear my 3rd grade teacher saying "He bought gifts for my friend and I." Judy is right, but if you can't decide, go with my friend and I. and if you start a sentence with this as the SUBJECT, then for sure use it. "My friend and I are ...." . Me and my friend, is to be avoided and all costs.

The custom is to use "My friend and I" as in "My friend and I are going to have lunch. " This usage is for the subject of a sentence. If it's the object of a sentence or a prepositional phrase, use "my friend and me", as in "He brought gifts for my friend and me". NEVER use "me" in the subject of a sentence. When someone says "Me and my friend are hungry." that is wrong usage!
