I suppose it wouldn't really require an entire book to propose that the 5 Love Languages are Worlds of Affirmation, Quality Time, Receiving Gifts, Acts of Service and Physical Touch. It is a pretty short book, but the anecdotes are effective. Apparently there is a book called "The 5 Love Languages for Singles", so probably I should have read that one, but I found this at Melissa's house. My primary love language is probably Acts of Service. I'm not sure what to do with that knowledge, but there you go.
