What they do is go around and yank off the leaves in protest. Some like to throw down colorful leaves, some prefer drab. Yank! Toss. Down floats the clueless leaves and clueless clonkers say, "Ahh, isn't fall invigorating, I think I'll go have some hot chocolate"
In my experience, faeries prefer spring and summer. Fall happens, as we discussed, due to repercussions from their leaf tantrums. To faeries, winter is utterly unhelpful. Wet wings. Wet garden parties. Intolerable.
These are some faerie doodles I did by going out in the woods in my leaf suit and sitting quite still. As soon as they realized that I was drawing them, they split.
