DEAR HARRIETTE: My sister, who is eight years older than me, showed up late to my wedding and missed nearly half of the ceremony. As my now-husband and I were exchanging vows, she made a grand entrance that was anything but discreet, causing a huge disruption. To make matters worse, she was wearing a white gown, which felt completely inappropriate and disrespectful. My sister has always been somewhat difficult, and I’ve tried to be understanding of her feelings, especially since she’s been vocal about her frustration and embarrassment over not being married at 40. I know that being single is a sensitive topic for her, but her actions at my wedding felt like a deliberate attempt to steal the spotlight and overshadow my special moment. It’s as if she couldn’t stand to see me happy and wanted to get back at me for finding my person. Should I confront her about how her actions affected me? – Jealous Sister DEAR JEALOUS SISTER: You absolutely should talk to your sister and let her know how inappropriate her behavior was at your wedding. She has to know better than to come late, wear a white gown and attempt to upstage you at this precious time.
