Corey: I thought you left (the Navy) because your eyes went bad.
Chris: Do I wear glasses Corey?
Chris: We're room-mates, we share a bathroom - ever seen me use contact lenses?
Corey: I just assumed they slipped a little below Navy standards.
Chris: 20/20/20/10 - my eyesight is better than perfect!
Corey: So why did you leave the Navy?
Chris: Because I can see the posters from across the room, but I couldn't see the knife coming from behind.
