I'll answer the question here: I chose not to walk because I wasn't graduating with my classmates. When it looked like I wouldn't graduate on time because my last full-time semester wasn't going to give me enough credits, I took a job here. Eventually, before my credits expired, I got slightly motivated and finished. I don't really know any of the other people I graduated with, and the graduation speaker was just the president of the university. Why bother?

My wife went to a big school. You get to "walk" in a departmental ceremony, the general graduation is just "whole department stands, is applauded, sits".

My sister-in-law didn't have the money for a cap and gown the day it was due, and so punted.

My brother went to the same school my wife did.

My sister must actually care. My diploma is in a pile under a desk at home. I will probably never use my degree. I don't care with a passion.
