The referenced article seems to tell a story of - initially - 4 very unhappy people.
The self centered bloke. The sacrificial chick. Kid 1 being stifled. Kid 2 being stifled. An altogether unhappy situation for the 4.
A while later ......... The chick eventually grabs the situation by the throat and off loads the bloke. He is - as far as I can see, probably still unhappy. Chick seems happy. Kid 1 seems happy. Kid 2 seems happy.
Actually, it would have been a good result had only 1 out of the 4 transitioned from unhappy to happy. 2 out of the 4 would have been an excellent outcome. 3 out of the 4 is fantastic.
