Mark was exhausted to the last shred of energy left in his body. Once he rested against the wall, sat down, and extended his legs there was no way he would get up. If those two strangers would suddenly decided to attack him and Rachel he would have no power to fight back. If the doors were struck open and walkers climbed up to devour them he would just sit and wait for it. He was in all terms and meanings fatigued and tired. Still thirsty. 

Mark set his wrench beside him, then he took out the expired skimmed milk and the small water bottle he found downstairs. He lines them up beside each other, then he took the water bottle and rank it all to the last drop. It wasn't even enough, but it was good to keep him alive and search for more. He could ask the strangers for water, but he was too tired to start a confrontation. 

Mark left the expired milk cartoon on the ground and succumbed unto sleeping. At first he hesitated to shut his eyes around strangers, but he was too tired and his body shut down.

Mark was woken up by the rays of sunlight coming through the window screens, hitting his eyes as he slowly opened them. The walkers had stopped and little groans were heard. The milk carton was still there, the now empty water bottle too. He sighed and looked for Rachel. The second floor was dirty and in quite a mess.
