Observing people...

These days, I have been taking public transportation to work.Though I am always lost in my own thoughts, I do tend to notice people sometimes. Oneday, someone in the bus just wished the other person ,asking where he works ..or something like that. The man didn't say anything..he was seriously typing something on his pocket PC.It looked as if it was rude of him(by not acknowledging). But then, he showed whatever he typed to the man who spoke to him. I then realized , that this man can't really speak anything other than saying "NO". They kept conversing..this man was typing his messages and the other man kept talking.
I suddenly felt, that he had such a disability(?) but still he is so happy, he even goes to work all by himself and seem to be content.
I do see people getting into the train, who are blind.
They do not expect or ask for sympathy. They take their challenges, win over them rather than giving up and waiting that something will happen.
When compared , we are all blessed to be normal. But we do have to win over some of our potential enemies such as procrastination, laziness.
