Discounted Denny's

I had just finished reading a very intriguing chapter in my sociology book illustrating death ceremionies of different cultural groups in the Netherlands when I began my way to my dorm. It was eight or so in the evening; there were still hints of light brushing the streets. I descended the stairs of the "PCL", also known as the library, and walked across the street to Jester. As I was checking for cars left and right, I noticed a middle-aged dude with a baseball cap shaking his head while he crossed the street in front of me. Noone else was around and I was wondering why he was making this gesture. My foot barely touched the raised cement and a bright figure caught my eye among the darkened scenery of trees. It was a naked old man! I took five looks. It was the utterly most traumatic scene in my experience with Austin. People always use the phrase, "I couldn't believe my eyes!;" When I saw the naked man with his (I'll say body parts) body parts exposed, that cliche became my reality. I walked inside because I didn't want to look stupid following some crazy, naked senior citizen around, but a little fear was in that decision as well. I mean what can you expect from some psycho flasher?
Today I went to a cardio express class at Gregory Gym. It was considerably challenging, but what was really interesting about it was the sole presence of this seventy year old male in the classroom. His eyes were low, and the corners of his mouth drooped; he showed little expression. He looked like he was about to die, yet he was in a Cardio Express class where even I, a seventeen year old normally active female, was having trouble keeping up. Of course he didn't know what he was doing and was having a difficult time, but he stayed the full forty-five minutes of torture.
I don't know what is wrong with the thought processes of these old people. I'm still trying to figure out what I should take from this. Help me out?
