Small counterpoint: I'm 42 years old, and I would have to look at my resume to see what year I graduated college. By time I graduated I was already working full time, had a contracting company on the side, and had a family. College was just a thing that was happening, another job, it wasn't a huge life-defining event. I remember the people I met and the projects I worked on, but there's no way I'd be able to accurately tell you the exact year it was over. (I just checked the resume, I was off by 2. Yikers.)

There you go, now you've met one!
