That’s not necessarily a truth. 

I am 48. I have children in their twenties and late teens. I have finally reached a pint of life where I can be friends as well as parent with my older children. It’s actually really nice and a fun and rewarding aspect to the job of parenting. 

But my point is  that I have found that because of this I relate better to people in those age groups now than I do to people (co-workers, acquaintances and friends) who are in their thirties. 

Nothing odd at all. And it’s pretty common for guys to it nature and have their shit together until they are at least thirty.
