Laying down is the most comfortable way to do nothing but stay still and do nothing, and you are a very intelligent bear for figuring that out. You lay your fuzzy belly onto the cool grass of the forest, letting your bear muscles and bones and skin relax into a nice spell of easiness and comfort. You ignore the hawk because why would a hawk be interested in a bear? That does not make sense, and you know that because you are a very smart bear.
You are so close to feeling absolutely safe. How do you get there, though?
