Post-College Boredom

I never thought I'd say it, but having graduated from college means a completely different lifestyle. There's no staying out/up late, because you have to get up early for work and you don't want to fall asleep on the job. Most surprisingly, I've found myself with a ton of free time; instead of having to work on a paper or think about classes all evening, I have nothing scheduled. So far, I've been amusing myself by reading, watching TV, playing video games, or desperately calling Jenny in China, hoping that she'll pick up. I wouldn't say I'm lonely, but it's definitely not as sociable as it once was at Stanford.

Is this college nostalgia?
