That pretty much sums it up for most people.
What's wrong with spontaneity?
When I first met DH he said that he was glad he lived too far away from his mum to do the obligatory every Sunday afternoon visits to her that his sister, her DH and DC did.
His mum was lovely, and we did visit her a lot because we never felt any obligation to visit. We went because we wanted to. MIL and I had a very close relationship and she told me that she told all her friends that she was delighted to have me as a DIL.
We also visited my family a lot because we wanted to and not because there was an expectation to do so.
In both cases we lived hundreds of miles away from both families so it was always a weekend visit, not just an evening.
15 people every Friday night is just too much, even for a sociable person like me, especially after a week at work and nearly an hour each way to drive.
DD is a student again at a university a couple of hours away. She hasn't been home since January until this weekend as it is a very full on course. I am delighted that she has settled well and has made friends. She is living her best life and, as far as I am concerned, if she is happy then so am I.
Being a parent is all about letting go, not guilt tripping your DC into visiting you all the time.
