The name of the song playing during the credits of Mr. And Mrs. Smith is "The Next Adventure" by John Powell.
Mrs Smith, unless she has specifically changed her surname back to her maiden name
Jane Smith
The name 'Mrs. Smith' is a proper noun, the name of a person, a proper noun is always capitalized. The noun 'class' is a common noun, not a specific name. The common noun 'class' is only capitalized if it is the first word in a sentence. The correct form is 'Mrs. Smith's class.'
The Honorable and Mrs. (first name with middle initial, if any) Smith
If the doctors name was Steven Smith, the correct form would be "Dr and Mrs Steven Smith".
mrs smith
In my opinion the desk name tag should say either Mrs Dianne Smith or Dianne Smith. Not Miss Dianne or Mrs Dianne. To be professional the tag should read Mrs. Dianne Smith or Dianne Smith.
Mr. & Mrs. Smith
She still is a Mrs. The women I know who have kept their names use the Mrs. with their own name. So, if she is Kate Smith and marries she becomes Mrs. Kate Smith.
"Me llamo la señora Smith" would be the literal translation, but a better way to say it would be "Soy la señora Smith", or "I am Mrs. Smith"
Mrs Robert Smith is appropriate, but more so would be to use her first name, such as: Mrs. Julia McGillicutty
Mrs. Kate Smith.
