Miss Manners: In-Laws' Wedding Gifts Oversight

A woman is upset that her in-laws, including her niece and her husband, did not give wedding gifts to her son and daughter-in-law, despite her extensive expenses on her own son's wedding. Miss Manners advises that reciprocity in gift-giving is expected but not obligatory, and suggests avoiding a lecture or confrontation, especially since the niece's response was rude. The woman also seeks advice on handling her friend's intrusive behavior regarding gifts, and Miss Manners commends her for being considerate.
