[Aside]
The point of Sour Grapes in the fable is simply a way that a person deals with disappointment “It really wasn’t all that great anyway”.
It can be used positively, as in “I didn’t get into Harvard, but is was never a good fit, the weather was too cold, I wouldn’t have fit in with the other students, etc. I’m really happy that I went to UCSD instead”. On the other hand, it can be used in a negative way, “I didn’t get into Harvard, because the only way to get in is to be a cheater or to know somebody, so they’re all cheaters and unqualified people anyway, so that’s why I didn’t go and went to UCSD instead”.
The difference between the two is that the first (who we shall call Janet) does not belittle the people who did get into Harvard, did not indulge in bitterness towards Harvard and the students there, and has some self reflection. I’m sure that Janet will enjoy college a lot more, do well, and forget about their Harvard rejection, except when somebody else says that they were rejected, and then Janet will say something like “I was rejected too, and I’m glad, because I had a great time in college, LOL”.
The second person (who we shall call Jason), belittles the people who did manage to get into Harvard, obsesses on the perceived crimes of Harvard, and does not spend any time on self reflection. Throughout their college years Jason will gnaw at their rejection, nurse their grievance, and likely waste a lot of time and emotional energy on dwelling on the unfairness of the world. This will poison Jason’s enjoyment of their college years, since it will all be colored with the taint of bitterness and anger. Jason will constantly have their rejection on their mind, and any mention of Harvard in any context can set off an unpleasant 10 minute rant.
Like the tale of Sour Grapes, this aside also has a moral - be Janet, not Jason.
