We have been married for a billion years, but my parents met when we first got engaged in 1998. Lucky for me my MIL's favorite movie is Crossing Delancey, so she was thrilled to find out her son was marrying into a New York Jewish Family! But it was fine...my parents are very warm and welcoming, while my in laws are appreciative of that, but I would not describe them as warm and welcoming. They are very reserved in their own way...I have never met a family who can avoid talking about issues like them. My MIL used to love to come to NYC for visits, but due to ill health, doesn't want to anymore.
But 15 years on, they really have no contact, they came to my sisters wedding a 7-8 years ago, and thats probably the last time we were all together. My parents come to visit me here maybe twice a year, and I always try to get my in-laws up so the kids can see their grandparents all together, but they ALWAYS have some excuse and don't want to come up! My parents JUMP at the chance to get on a plane and come visit me here!
In laws. Meh!
