The dog eagerly proceeds down the dark hallway. You aren't so sure about this...
You walk down the hallway anyway. After all you have a companion to keep you safe...right?
You and the dog come upon a lonely glass of water standing on the floor, at the end of the hallway. In front of you is a dead end.

You realize how parched you are, but notice the dog is also very thirsty.
You have a choice to make. You can either give the dog the water, or you can take the water for yourself.
What is your next course of action?
