How do you know it's love?

Adelina lights up whenever she (or anybody else) mentions Ruby. I told her I noticed this, and asked what she feels when she thinks about Ruby. Where is the feeling, inside or outside of her? She drew a picture of the people she loves. Then she created a beautiful metaphor for the feeling she has when she thinks about Ruby, Aurelio and her family. She said "There's a great, big circle around me and Ruby. The circle is  music, and we dance. When I feel love, flowers go all around me."
