There are many relation in life so we always communicate with everybody in this society. So what the first thing you notice a new person you meet in your life: their voice, their face and hair, their clothes and something else. In myself, I regularly see their eyes, teeth, facial expression and their clothes.
Eyes:
There is one sentences “eyes is the window of spirit”. Thus, eyes say about everything in our mind such as happy, sad, eager, honesty, shifty or something like that. And when I meet a new person, I always see in their eyes which express a part of them. I can guess whether they want to say with me or not. In addition, when seeing their eyes, I can guess if their words is honesty or not.
Teeth:
I do not know why I see their teeth when I am talking to them. But that my hobby and I also see their teeth is clean or not. This seems stupid ^_^
Facial expression:
Everything will show on your face when contact with everybody so I always notice the facial expression of the opposite person. I want to know whether they hear and care everything I said or not. If they really notice in my story I will to continue and I will stop talking if their face show bored.
Clothes:
I am an neat person so I really like to see people in clean clothes. That is reason why I always see the clothes of person I meet and talk to. I feel comfortable to talk to a person with dress neatly (just need to neat clothes not to need beautiful clothes). And I am always unpleasant with people in untidy clothes.
