In our family I am the one who is 'disconnected'. I very rarely phone anyone (AC, GC or my siblings), I may text occasionally if I have something specific to say. I love them all to bits and think of them all the time, I just don't feel the need to constantly be in touch.
It seems to be a trait in my family as my brother never phones, writes, texts, emails or visits. He doesn't welcome visits and has never even met my children. I always send him birthday and Christmas cards but he never reciprocates. I just accept that's the way he is.
As for family events and get togethers, our AC and GC visit us several times a year, they organise visits as they have work schedules, school etc. They also visit each other and keep in touch frequently.
My own siblings are scattered around the globe and the older we get the less keen we are to travel long distances, so now it's just weddings and funerals, health and mobility permitting.
