Nick couldn't stand Coach's deep snoring. It echoed through the safe room, keeping him awake. It drove him mad. He tossed and turned trying to find sleep so his exhausted body could finally rest. He had no idea how Rochelle and Ellis slept through it.
Rochelle hardly noticed Coach's snoring. Her old roommate in Ohio snored. She tended to zone out and found it easy to fall asleep through the snoring. It probably helped that she was so physically and mentally exhausted that she didn't care.
Ellis would never admit it to anyone, but he liked Coach's snoring. Hell, he could say he enjoyed it even. Coach's deep snores rumbled through the safe room like a deep woodwind instrument from a blues and jazz festival. It helped Ellis relax and sleep.
Coach, on the other hand, denied that he snored, which pissed Nick off and made him bitch, which not one of the survivors enjoyed.
