If it weren't for the clue that he could hear the song on the radio when no one else could, this could be any couple. This whole thread started as a list of Elvis song titles, so I wondered for a minute if it was Perry and Alice or Jonathan and Martha, but that wouldn't fit the other clues.
I wasn't back on the boards yet when the Elvis song titles thread started, so I didn't know that folcs might think the characters were anyone but L&C. It's kind of cool, though, when you think about it, isn't it! Perry and Alice, or Martha and Jonathan ... they are devoted couples too. I could definitely see either one playing the kissing game. :-)
Thank you for the nice feedback.
