Etiquette comes from education (Onisi Oss)

Etiquette is more important than law. Its elegant characteristics have built an insurmountable protective wall for itself (love of life).

Self-esteem is the most insignificant in etiquette. Politeness is a sign of being educated and friendly, and it is also a respect for the rights, ease and feelings of others (Ralph Martin)
