Emotions in a Security Line

Not sure how I made my 5:45 am flight out of Baltimore this morning...I was running pretty late. Either way, I really dislike the emotions that I feel in a security line when there is the risk of missing your flight and the line stretches down hallways and around corners. From nervousness to anger to sheer impatience, frustration and fear, it is not a pleasant way to start the day. And then, when you get through and you realize you're going to make it, you try to put that all behind you and go back to being normal. I am not very good at packing away emotions after they surface.
