It is three in the morning on a Tuesday, and I’m walking toward table eighteen, the one I call home. I pass the waiters, give a brief nod to the  小题1:  and take my seat. I  小题2:  the “usual,” water and peanut butter pie. Yes, I’m at an all-night diner.
I start to take out my books,  小题3: full well that I will be  小题4: on the same page of Socrates that I’ve been on for the better part of the semester. Of course, it’s   小题5:  —for my group that is. I wait for the empty chairs around me to be   小题6:  .
Just as the Muzak songs start to repeat themselves, Shana and Jenny walk in. I am   小题7:   with the usual big hugs and smiles. 小题8: , the diner stops being a twenty-for-hour restaurant with bad service and becomes my place—my home   小题9: the prisonlike dorm room. For the next couple of hours, we will joke about people we know, talk about books, reflect on the meaning of life, quote movies and  小题10: new private jokes. Table number eighteen is our  小题11:  home.
During my senior year of college, I started going to the diner for a temporary escape from a dorm room that felt like it was closing in on me. Not to 小题12:  the phones, the stereo and the computer. How could anyone seriously  小题13:   to have good study habits? Some friends of mine told me about the place; they went there to study, and they really liked it.
So I tried it. It felt remarkably freeing. I start going there every night (except weekends, of course), and, believe me it was not because the pies were   小题14:  great either. Maybe it would force me to open my books and my  小题15:  would improve. Right? Well….
But that’s not the   小题16: . I mean, anyone who has gone to college knows that it’s not only about forcing yourself to wake up at 7:45 A.M. (after you had gone to sleep two hours earlier) to listen to a professor spoon-feeding you information  小题17: the significance of the Battle of Hastings. It is  小题18: about finding a little haven where you can create what will be the most important thing in your life—yourself. At a school of thirty-five thousand people, I found a small place that was as   小题19: to me as my Social Security number.
Through laughter, tears, learning, growing and the   小题20: free ice cream, we found a sanctuary. A place where we could be ourselves.
