I always say "fine" too because the reality is often to complex to explain in a quick chipper manner, and 99% the person asking probably doesn't even want to know!
How am I doing? Physically, I am heathy minus my being overweight. Emotionally, I am stable though I must admit melencholy brought about by the isolation from my peers on campus due to me being a 23 year old sophmore (kids, go to college as soon as possible!)
I'm also stressed from myriads of essays that I am writing, one particularly demanding professor who happens also to be the Abbot of the Monastery intimidates me a little, and I am missing a handful of people who are nearly 1000 miles away (not my parents, either). But, I am comforted by the encouragement I recieve from the monks on campus, from Christ, and I am glad that I found my coffee filters...hahaha.
