I'm stumped about how to start my thank yous to the numerous middle aged couples who are friends of our parents. Should it be "Dear Mr. & Mrs _____" or "Dear
First Name &
First Name". I plan to do Mr. & Mrs. on the mailing envelope.
On one hand they signed their first names on the cards they gave us at our wedding, so it may seem impersonal to not address them each by name. Yet, for some of these couples, we hardly know them and I wouldn't want to come off as rude, so maybe it's safer to go the Mr. & Mrs. route...?
Thoughts and advice appreciated!
