A daughter-in-law should tell herself, “My mother-in-law raised my husband and entrusted him to me. I should be thankful and respect her as if she were my own mother.” Similarly, a mother-in-law should also recognize, “My daughter-in-law’s parents put a lot of effort into raising and educating her. Now that she is part of my family and helps to look after my son, I must be grateful to her and love her as my own daughter.” Mutual gratitude is the key to maintaining a harmonious relationship.
