These young people are in the Love for the Elderlies Movement. This movement focuses on reaching out senior citizens by honoring them and taking care of them. Each heart’s desire is to show the love of God to them, letting them know that they are important to God, never overlooks them and loves them so much as He loves the young and the adult.
I hope this will encourage you to honor your grandmother and grandfather and even your parents. Godbless you!
