My son lives less than 20 miles away, I am lucky if I see him twice a year. His wife sadly does not believe in including family in their lives, but is happy with her own little unit, their daughter and work. They both work hard and very long hours, but do have days off occasionally. When I see my son it is only him, he usually takes me out for a couple of hours for a meal to celebrate Xmas and my birthday. I have not been to their home for 20 years, but do visit their work place to say hello if I pass which is not often, because they are always to busy and do not have time to make me welcome although the staff offer me a coffee. He is very generous with birthday and Christmas presents. HOWEVER I know if I struggled and asked for a favour it would get done. I have so far never asked but just know my son would be there for me. He will text if there is something he thinks I HAVE to know, like when my granddaughter passed her masters etc. but I am never invited. I miss them, but have a busy life doing voluntary work so life goes on. I personally think sons are very different to daughters. I see the similarity with most of my friends.
