Mary-Beth sat on the floor beside the campfire next to you. She listens to the others talk and sometimes talks too. She is clearly stressing over something. She won't stop biting her nails. You make eyes at her but she doesn't get the hint. You put your hand on her wrist and gently tug her hand away from her mouth. She looks at you and you wrap your fingers around her wrist and move her hand away from her mouth.

"Um.. What are you doing?" She asks you, completely oblivious to the reason why you moved her hand away from her mouth. Her expression shows confusion but she doesn't try moving her hand away from your grip.
