A can a day Grizzly Mint Long Cut habit.

Stickler for time, irritation with lateness like it's socially acceptable, hair cut style, manner of speech in addressing people, (sometimes good; yes sir, no sir, other times, not so good like R. Lee Ermey in Full Metal Jacket), general irritation with civilians, sickness I feel when people thank me for my service (more of a feeling of contempt and disgust on my part, hightend sense of awareness, distain for authority, other than these little "quirks", I'm really a teddy bear! Lol!

24 hour clock, phonetic alphabet, left foot first when stepping off.

Keeping my hair short, arriving early to meetings and walking at a brisk pace even indoors. And spelling phonetically to people when I need to.
