Answer:
I am a way to say goodbye to your sweetheart
I have roots nobody sees. I am taller than trees. Up up I go but I never grow.
The more of this there is the less you see. What is it?
What is harder to catch the faster you run?
Iām grown from darkness but shine with a pale light. Very round I am and always a lady's delight.
What do you purposefully put lots of in and on your body, but run away from when you encounter it outside?
