Others here on the island fly their college flag in front of their house, and have a college sticker on their car. They have made an identity for themselves based on what school they went to. And I guess some folks need that - some pigeon-hole to put themselves into, as left to their own devices, they cannot figure out their own identity. So they latch onto college as a means of drowning out the deafening silence in their lives.
I think his experience was like the college visit scene from About Schmidt - where Schmidt goes back to the University of Nebraska, and bores some young college kids at his frat about his work as an Insurance actuary. It is really irrelevant to them, and college at this point was irrelevant to him. It's like the scene where he goes back to his childhood home and finds a tire store.
And yes, we've gone back to our childhood homes before and laughed about that scene - expecting to find a tire store, but instead finding only a house without a lot of emotional impact or in fact, any sort of closure or whatever. There is little profit in the past, other than to learn from it.
And the same is true of college. Get your degree and get out. Just as High School is not an end in and of itself, but a means to an end - something those stupid kids who shot up Columbine High School simply didn't get. Don't like High School? Most people don't. Graduate and leave. Most people do!
And while college is generally a better experience than High School, obsessing about it decades later is, to me, kind of sad.
