"I have to get some sleep." You replied.
"Okay," Ryan said, closing the door.
For that day you slept. At night, you got your clothes on and set for work, guarding the building.
You took a hunting rifle and stood on the roof with about six others. You never knew them well. A few hours into the shift, a gunshot is heard. You tun around and see one of your comrades, lying on the ground, bleeding. You rush up to him.
"Who shot you?"
"What? Are you serious?"
Before he could finish another gunshot is heard, then another. Soon came a volley of bullets into the building and a crashing sound.
