Mr. C would like to be known as Maj. C, his proper title. And if that is the case, I shall be Dr. H, my proper title. And our sprog will be known as "Bunny," which not her proper title.
That said, I shall always be Mrs. C to Mr. C.
Addendum: Maj. C would like it be known that the proper US Army abbreviation for Major is MAJ. However, due to a misspent youth in the UK, MAJ looks funny to me. And as this is my blog, I hear by say he is Maj. C.
