Not usually b/t siblings of 20-ish age, though...well, not in my part of the south anyway.
Mine either, Capri! I have 4 brothers and have never been called an endearing name by them! And, if anyone who does not know me uses an endearing term such as honey, darling, etc., I take offense to it.
The Anthony family have a habit of calling Casey names such as Sweetheart by Cindy, Gorgeous by George, and Darling by Lee. WTH?
