which is correct?
John and me
John and myself
John and I
It depends on the context (again)
Are you talking of John and you as subject, or as object?
"It was good for john and me"
Not a teacher, by the way.
I = subject of a sentence (John and I are tall.)
Me = object of a sentence (John told me he was tall.)
Objects: The film was great for John and me
"myself" is used to emphasize I as subject: I myself did not like the film, or as a reflexive pronoun: I saw myself as hero of the film, and on occasions as a replacement of I or me. This is usually regarded as not quite correct, but is found colloquially.
I knocked over the glass and got water all over John and myself.
