My four day journey took me straight to Boot Camp where we had our own drill instructor. Even though he gave us about 50% of the yelling and screaming and running around that they give normal recruits, it was enough to help me understand the process. Standing in line, waiting to urinate and hearing "Move! Hurry up! No one waits on you!" was enough to make me nearly pee my pants. We were marched around, told we weren't doing anything right and made to "Step it up" over and over. Nothing we did was good enough. No amount of shouting was ever loud enough. And I could tell our drill instructor wanted to put us in "the pit" (a pit of sand where you do push-up, mountain-climbers and more while being mercilessly yelled at). Luckily, as educators, we were spared that part of the experience.
Semper Fi.
