I am constantly amazed at how different folks react to different situations. Make no doubt about it, it very well could have been a reversed situation with the parents. However, in this case we see that success and living in a 'rarefied' atmosphere calcified, rather atrophied familial harmony. Yet, on the other hand we see a set of parents who would have every reason to complain bitterly about the inequities/struggles of life, understanding not everything is black or white. At great sacrifice to their personal condition, scrimped, saved, and found a way to afford the means to provide a college education, the full-boat scholarship non-withstanding, sent their son off to college with those funds to ensure his education would be his primary focus. Contrasted to parents who distastefully sent their son off as an embarrassment to be avoided amongst their peers and relations. Not for a moment regretting their decision, much akin to treating their son as a bad rash, hoping it will respond to the 'cure'...
The best outcome is for Manny and Robbie to live their lives fully with the family they make, and someday the family they raise. To be successful in their careers and remember the most important dictum..."You can pick your nose...but not your relatives".
Let go of what is beyond your control and live your lives as every day together is a blessing to be cherished.
