Privacy
When someone does something that is not praise-worthy at all, or if he or she messes up, you need to tell him or her in private. This may not always be how it is done in the military, especially not when you forgot to make your bed correctly. However, they often deal with mess ups in private. So, even when you are back in your regular life, you still do the same thing.
On Your Feet
When someone speaks to you, you always stand. It doesn’t matter whether they were only asking you what you want from the store, you give your answer on your feet anyway.
