I have recently been considering the correct use of "I" and "Me" in this particular case; Someone posted a picture of themselves, standing next to a celebrity, on a social media site, with the caption "[Celebrity name] and I". As the poster is a friend I was about to correct this to "[Celebrity name] and Me", but the more I thought about it the less certain I became.
I am usually good with "I" and "Me" and I understand how to use the handy rule of thumb to remove the "other person" to see if the sentence still makes sense. But in this case, there isn't much of a sentence to remove. However removing the reference to the other person would leave the caption as "I", which seems wholly wrong to me. But then I remembered that there is a style of speech where a person can refer to themselves this way- "'Tis I Sir!"...
So realising I needed to understand more about the use of the personal pronoun, and having no prior education is the finer detail of the English language from a grammatical rules perspective (that I can remember!) I went looking.
I found out about the Subjective and Objective case that defines this use and tried to apply that knowledge to the problem. However given the original caption I couldn't figure out whether the personal pronoun is the subject or object. I imagined the caption expanded into two sentences:
- "This is a picture of [Celebrity name] and me"
- "[Celebrity name] and I are in this picture"
How should I correctly parse "[Celebrity name] and I" to determine whether the personal pronoun is the subject or object, and whether, strictly speaking, "I" is allowed due to the older speech style or not?
Use of "I" here seems like a hypercorrection to me, but am I right or am I missing some subtle rule given the brevity of the sentence?
