White house on a Hill Top

I am so tired today. I don't know why. Am I tired because I am an old man? Or am I tired because I am sick?  Since, it's impossible to have an experience of an old man's life when I was young, I wouldn't know how I feel like when I get old.

First, one of my friends Jay came to my house in the early morning, and another friend Noel came by right after he left. We went to lunch and we had busy time until three PM. That's only thing I have down  to day. But I am so tired. I am going to bed as soon as I finish writing a diary.
