This song is for newly married Amy, her husband and their children. I hope to get to know more about their story, but true love is definitely a part of it. (and I promise I am not cyberstalking them)
In my experience when you are with someone you truly love on a multitude of levels, the everyday minutiae can feel like a dance, a compromise - "I'll light the fire, you place the flowers in the vase you bought today." Even if the reality is "I'll clean the poop off the wall, you heat up leftovers yet again." When you have that love on many levels - you can laugh at life and continue to dance.
True, authentic happiness is so much more about your perception of reality and changing your attitude towards reality then if you got dealt a good hand in life.
