Facial Features

I've started to watch people's faces more as they talk. It has in turn made me more cognizant of my own facial expressions. Now whenever I talk I consciously think of how my face must be looking. There is one person who I've talked to a couple times today and she rarely looks you in the eyes, laughs with her mouth open, and always say, "Oh, boy". When she does she usually has her hand on her forehead, her head is tilted back and she stares at the ceiling. There is another person who I've talked to a few times. He makes direct eye contact (it's unnerving) and his nostrils suck in when he breaths. He never smiles, and his nostril thing is very distracting. The two ends suck in and sometimes it's all I see (so bad, I know).
