He really likes being with you.
A week ago, you had been brought an offering. A tiny man, squirming around and screaming for freedom, he was set in your palm and suddenly... calmed down.
For a week now, you, the leader of your small tribe, has been taking care of Ebony. He likes life with you- it's comfortable and you provide for him. He gets to sit by the fire as you feed him fresh grapes, snuggle in warm animal furs. Being brought to you as a gift was the best thing to happen to him.
Meanwhile, the people of your tribe have never seen you so gentle and so happy. It seems Ebony has somehow softened your heart. Every night, he sleeps tangled up in your hair. He says it's warm, and it smells nice. Since he's only three inches tall, it works. So when you wake up this morning, you're not surprised to feel him squirming in your hair.
