A bit apprehensive...

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."
