For those younger troops that are fresh out of training courses and do something that gets them in trouble at home:
153. You start to come to attention when you hear someone yelling at you (usually a parent, but could be a teacher as it was once in my case)
I had seen a professor about an paper a few days before it was due, and he had read it and told me that it was a good paper but to make a few changes. I had been up all night working on the changes the night before and came to class early the next day, filled out a teacher evaluation form, and realized I had forgotten my reference page. I returned to my room, picked it up and then went back to class. When I arrived a few minutes late, the teacher jokingly said "Oh, this one‘s fresh off the printing press coming in late like this..hehehe"
I jokingly responded, "Acutally, it‘s time for me to go to bed now"
I turned smiled and turned around to go to my seat but the prof started screaming at me in front of the entire class.
"That‘s the most disrespectful, irresponsible thing I have ever seen a student do in my eNTIRE LIFE!!!!!" (his tone raising to a scream by the end of the sentence as his face turned bright red, partially due to anger and partially due to an alcohol problem) He then continued "I WANNA SEE YOU AFTER CLASS!!!! YOU BETTER BE BACK HERE AFTER CLASS"
At that point, I had found myself coming to attention, and was far too embarrassed to try and explain to him that it was a joke so I left and returned after class to sort it out.
