Is it correct to say "Me and my friend, we..."?
Solution 1:
Given that these are acceptable:
- Me, I went shopping.
- Us, we went shopping.
- Her, she went shopping.
- Him, he went shopping.
- Him and her, they went shopping.
- Them, they went shopping.
Then that means you continue to use object-case pronouns in emphatic position, no matter how many of them you happen to find there:
- My sister and me, we went shopping.
- Him and her and me, we all went shopping together.
The Moral of the Story: Joining two object-case pronouns with a coördinating conjunction doth never a subject-case pronoun make.
