Being the older, wiser man is a power trip for him.
And that's all about , the said power trip he is getting off on should be overt.
He owns his own successful business although he still lives with parents.
I know its only 8 years difference but it's the difference between him being at an age where he must be thinking about starting a family, marriage, etc and her starting out in life. Do I let them get on with it or should I try to explain my above concerns at the risk of pushing them together? Based on the logic, it shows that "Reductio ad absurdum." I was 19 and ran off with a 27 year old woman from America. My mother disowned me and we didn't speak for a year. I was reckless and foolish and as an adult 20 years later I can easily recognize this.
It's because of this urban legend that has gone around forever.
