Appetite (or lack thereof)

I don't know what it is, but I can't usually eat when I come back to school. Do not be alarmed, I DO eat but my appetite is not usually strong. Part of it has to do with the school cafeteria food. Last night, the only remotely appetizing things I had was pea and rice soup (!), celery, and chocolate pudding. Today's lunch was a little more hearty -- I had a sandwich, fettuccine, and celery. Nonetheless, I still couldn't finish all of it. This is why I usually eat healthy, and end up losing weight, while at school. It's just a fact of life.
