The Five Love Languages

Just what are 'The Five Love Languages'?  As Wikipedia explains:

"The Five Love Languages: How To Express Heartfelt Commitment To Your Mate is a 1995 book by Gary Chapman.  It outlines five ways to express and experience love that Chapman calls "love languages": 1.) gifts, 2.) quality time, 3.) words of affirmation, 4.) acts of service, and 5.) physical touch.  Chapman's book claims that the list of five love languages is exhaustive.  Chapman argues that, emotionally, people need to receive love.  He also writes that people should not use the love languages that they like the most but rather the love languages that their loved ones can receive."
