I always love that feeling of collective "Ahhhhh" from all of the plants I see... And extending the feeling to the birds and animals and all living things.
When we had an extended drought and finally got some real rain, I had a fantasy conversation with my kids about how some of the baby birds and animals born earlier in the season had NEVER experienced rain in their entire little lives.
Baby Bird: Mama, what's happening? What's that stuff falling from the sky?
Mama Bird: Remember the stories I told you about rain?
Baby Bird: It's, it's... What is this feeling? It feels good!
Baby Bird2: It's called "wet." Mama said so in the stories.
Baby Bird3: Lemme feel! Oooh, it's shiny.
