Let us suppose that two people meet for the first time. Their meeting brings together different sets of hereditary qualities and the products of different environments. How will these people react to each other? Neither is entirely capable of judging him, but each will judge the other during the meeting. Judgment will be based chiefly on two factors: appearance and behavior.
Although you may not think it always fair, the first thing people notice about you is how you look. Your appearance may invite closer acquaintance and friendship, or immediately cause someone to ignore you. Think of the people who have made the most favorable first impression on you. Certainly they were not all handsome/beautiful or striking in appearance. Chances are they had one thing in common; they made the most of the qualities their inheritance gave them. What is your reaction to a person with dirty skin and fingernails, used hair, and sloppy clothes? The chances are that your impression is unfavorable.
