An old person I know

I want to talk about one of my friends, Tom , who was also my classmates in college.

We both are living and working in B.J,China. We have a deep conversation once per week, and share what we've learned in the past week. He is honest, brave, and sunny. He likes playing basketball, and always dedicates himself into it. He is careless and mindless, and always forgets to take his keys when he goes out. He is a workhorse, and enjoys himself everyday.
