I want to sign a letter jokingly not by name, but by a personal pronoun. Is the signature a subject or an object? I feel like using object pronoun (me) sounds better, but why? The signature looks more like a subject to me.
Example:
Best regards,
I
or
Best regards,
me
And for more people signing the letter, following the rules from Which is correct, "you and I" or "you and me"?:
Looking forward to your answer,
John and I
or
Looking forward to your answer,
John and me
ADDED:
Based on the @wjandrea's comment under Peter Shors's answer, can the ellipsis
(This is) me (signing that letter)
be used as an explanation why the default pronoun is the objective case?
Best Answer
The default pronoun to use in English is the objective case. See this EL&U.SE answer. For example, if you were to label a picture, you would label it "me at the beach in 2011" and not "I at the beach in 2011".
The signature is neither a subject nor an object, as it is not part of a sentence. Thus, the correct pronoun is "me".
