As a sergeant in a parachute regiment I took part in several night-time exercises. Once, I was seated next to a Lieutenant fresh from Jump School.
He was quiet sad looked a bit pale so I struck up a conversation.
"Scared, Lieutenant?", I asked.
He replied, "No, just a bit apprehensive."
I asked, "What's the difference?"
He replied, "That means I'm scared with a university education."
