One night I was going to work on my usually bus route. Upon our arrive at the terminal, I noticed that I was the only passenger left on the bus. I looked around and saw a mobile phone in a chair that must have been left behind by the passenger. I give it to the conductor.

Two day later, the conductor told me that the passenger was very much happy that I returned the mobile phone. The passenger was trying to get her name, so she wanted to post on Facebook about what had happened as a sort of appreciation. I thought it was unnecessary. What was important was when I saw the smile on her face, I was happy.
