This book is just perfect for those days when you wake up feeling down and just want to be left alone. It tells the story of two siblings - one trying to cheer up the other with fun activities like coloring and baking, but the other just wanting to throw rocks and kick leaves. As they express their feelings, the younger sibling starts feeling better and ready to hang out again. It's a beautiful reminder that it's okay to feel blue sometimes, and that talking about it can help us feel better.
