Values are things we prefer or give importance to. Honesty is a value and so is teaching an impressionable mind (of the children) the worth and importance of honoring dead loved ones.
The values are "CAUGHT" and not "TAUGHT". Meaning the value of remembering our grandparents on All Saint's Day is better learned by the examples set by parents by watching them live out on November 1st and not by doing lectures.
Values are part of the child's life experience. If parents attempt to lecture why we need to go to the cemetery to honor our loved ones ... well, they are good values all right ... but not totally the children.
