Mine has called me "my dear" twice. The first time I convinced myself I misheard it, but the second time it came out clear as day. I stopped and stared at her and said "did you just say that?!" and she was like "it just came out!!" She hasn't said it since, lol. It wasn't really a problem though, I just really wasn't expecting it. It might have been a problem if it happened earlier on, though, when I still had to be in a place of denial that she had any feelings about me whatsoever.
