Last summer, my daughter sat in the middle of our yard blowing thousands of dandelion fuzzies into the air. She did this on a regular basis for a few months. Every time she was outside, she would pick the flowers and blow until all that was left was a thin green stem with a tiny knob on top.
I sat with her one day and explained that the fuzzies that she was blowing were actually the seeds to the dandelions and that if she continued to do that, we would have a yard full of the yellow weeds in the spring.
She responded by telling me that she knew all of that and that she was doing it on purpose. Dandelions were her favorite flower.
Today, I glanced out the kitchen window. The entire back yard is carpeted with bright yellow dandelions. I'm sure my daughter is happy.
Did I mention that she is nineteen years old? :)
