I know this is a silly question, but I've never been able to figure this out. If my sister and I have a favorite song, how would I describe that fact in a sentence? "That's my sister and I's favorite song", "that's my and my sister's favorite song", "that's my sister's and my favorite song?", or some other permutation I may not be seeing? [more inside]
I understand the normal rules for "I" and "Me" in sentences, but I simply cannot figure out the answer to this example. What I want to say is that my dad and I are regional truckers (or me and my dad are regional truckers). If I stay true to the "I" vs."Me" formula I learned in school and eliminate the objective pronoun, the simplified version of the sentence can be written as either "I are regional truckers" or "me are regional truckers", and both of these look atrocious written down. I'm not a seasoned grammarian, but even I know that neither one of these seems to be the correct answer. Am I missing something?
