Super ears

I'm very glad this week is coming to an end.

Had attended a course for the past two days. Although the subject was a really boring one, the trainer made it tolerable (pleasant, actually) by injecting his humour and illustrating lots of real-life examples in the workplace. I think this is the best course I have attended so far.

I went back to the office to clear email. The mailbox had exploded beyond my imagination. Tomorrow I have got to maintain my cool. I have to I have to I have to.

While on the way back home, I saw an old man with a white walking stick. I thought he looked like he was visually handicapped so I walked a little slower, just in case he needed help or walked onto the road. When we reached the bus-stop, I stood beside him. As I waited for the bus, I observed him. He looked to his right and then to his left, to his right and then to his left. He looked like he could see. However, he never looked at me even though I was practically looking at him the whole time.

As the buses arrived, I wanted very badly to ask what bus he wanted to take but I didn't. I was afraid of offending him (he really didn't look like he had any difficulty). After a while, he just walked briskly (without using his walking stick) to sit down at one of the seats at the bus-stop.

I just kept looking at him. After a while, when a bus got to the bus-stop, he stood up and mumbled a word or two to the stranger beside him (I couldn't hear but it looked like he was confirming the bus number) and he got up the bus with ease.

I was so amazed. How does one differentiate between Bus A, B, C etc. by using his hearing?!? Is it possible?
