I know a boss secret. If a person in authority over you has to give you some bad unwelcomed news they can avoid direct contact with your eyes. This happened to me twice, once when they downsized me from an office job and once when I was told I didn't get a job. The person looked right beneath my eyes. It's probably a little bit of a distraction for them too as they stare at your dark circles or bags. They can roll the bad news off their tongue without thinking too deeply as they may also be thinking, "Man, that girl needs some sleep or her allergies must be acting up, or she must have an iron poor diet!".
