I am a 36-year-old guy. For the last 10 years, my mom has invited me to Passover Seder. I never go. Religion is not my thing. But this year she didn’t invite me. We had a good talk the day before the dinner, so I don’t think she’s upset. But I heard from a cousin that the Seder went on as usual. I can’t help feeling insulted. What should I do?
