you go to the left

You follow it to the left along the river and start to climb a small hill. The path grows steeper and rockier and soon you are facing a small cave, just tall enough for a man to stand upright in. In front of the cave lies what appears to be a black pile of fur. Moving closer you can see that the fur pile is moving up and down with slow, even breaths and hear the snoring sound. Realizing that this is not a pile of fur but a very large bear, you are faced with a choice:

Do you wake the bear

or

do you hurry back the way that you came and pretend this never happened?
