An afternoon chat on the pleasant nature of cute names for romantic partners (edited for content and ease-of-reading):

Them: Someone started calling me sweetheart last night. :-D
Me: Oh good. I like cute little names and the intimacy they imply
Me: Me, I talked to my grandma last night (to wish her a happy birthday). That put me in a good mood
Me: One day, I'll have someone call me sweetheart and mean it in a romantic way
Them: Yes, I have no doubt whatsoever that you will. You're a mighty fine catch and you deserve someone who appreciates that fact
Me: :-)
