Families (mine included) are just too busy. Working, commuting, homework, trying to get some exercise in. Any spare time I try to spend it with my children.
I always look at happiness in terms of pillars, social, family, work, spiritual. Work somehow has taken over everything. It seems culturally engrained.
I know social media is a factor but while we all fall down the rabbit hole occasionally, it doesn't stop anyone organising a get together.
