I was just trying to think (ow ow), and I don't remember my parents having pet names for each other (well, except in their old love letters!) even though they were mushy and kissy always.
I'd probably have a heart attack if my husband called me "dear" or "hon". Come to think of it, I don't call HIM pet names, either, but I don't call him Hey You! I don't think...
He doesn't yell at me or swear at me or tell me I'm stupid, or call me Chubby or Bimbo, so I don't care if he EVER calls me by my name.
