Life Lesson.
Expect to be killed when you run out of ammo trying to shoot someone else down.
Expect to be HO'd when you go head to head.
Expect to be killed when you are on fumes and want to leave a fight.
Expect that your expectations of people will not be shared by others.
Then, when you are let go, are waved off with a salute and well fought message, and generally left with warm wishes you will be surprised, but pleasantly.
Expect and Prepare for the worst, hope for the best. If you always expect they will do something other than you want them to do, you will never be disappointed or let down. Much easier thing to control ones own expectations than the countless numbers around you.
