Another quote from Staff Sergeant Old School that’s spot on. I was never in a rifle platoon, but I did serve in the U.S. army and work in a medical unit in Iraq. And I can tell you from first hand experience, that even in war, I never laughed harder than with some of my army buddies. You’re working 24hour shifts, going weeks without down-time, you’re starving, tired, pissed-off, and yet you still somehow find yourself able to laugh with your friends–even if it is about how tired, starving, and pissed off you all are.
