I don’t know if it is because John and Jarrod always had ‘older’ people, men and women, who gave them attention and mentored them - and yes, even played with them, but John and Jarrod seem to have a natural tendency to ‘be with' and play with their nephews and let them hang with them without any reservations.
From early on John and Jarrod had first their older sisters who played with them, regularly. Then, through Boy Scouts they were often with older men and teenagers. Then, people like Stacia, who became a big sister to them and so many others from church.
Now, the boys, young men really, are giving back. To their nephews. APR ‘19
