The customary way to welcome or congratulate someone is to present him or her with a lei, a garland of flowers (or other decorative items) strung together and worn around the neck. One puts the lei over the recipient´s head and if the relationship is close, gives the recipient a honihoni or a kiss. Lei are especially appropriate for high school and college graduations, birthdays, etc. Lei are also provided to keynote speakers and dignitaries at public functions (generally anyone with a public title, e.g. politicians, religious leaders, school principals).
