Why do we think so much?

I generally go to the Forum mall in an auto. That is, whenever I come to Bangalore. It takes Rs 65 to 80, depending on where I start. For the last two times, and that is when I went alone, I gave almost Rs 65-70 to the autowallas.

This time my Jijaji introduced me to a new option by telling me the number of bus going from home to the Majestic. (although its an altogether different matter that I always come from Majestic to home by bus only, I never cared to notice the bus number as I know the platform there)

So I reached the 18th cross bus stand crossing the cricket ground in front of the home and caught bus number 252 to Majestic. There were no seats in the bus and I was standing all the way. No big deal, actually.

Reaching Majestic, I asked a conductor where to get a bus to Kormangala. He told it was just in front. I reached the place he had pointed towards and with my aadha-adhura knowledge of Kannada (only written, I can't speak a word, except beda) I read it was for Kormangala only. Getting nearer I realized I could read in English also as the small lists of stoppages were bilingual.

As soon as the bus number 171 came, people gathered at the gate. The passengers from inside the bus came out and then, I know I was inside the bus, and somehow found a seat.

Almost 5 minutes later, the bus was full of crowd and there was hardly place to stand. Just next to my seat there was an elderly person standing with a bag in his hand. I'm not very good at guessing age of people but he was not less than 50. I cannot say whether he was below 60 or even more than that.

Seeing such an aged person standing beside me, I felt bad. I thought I should offer him my seat as it was not a big deal for me to go standing in a city bus. I do it half the time I travel in city buses. But I was thinking, and thinking. At least ten minutes I was thinking before I actually offered him my seat and he asked me something in Kannada, most probably it was if I was about to get down. I didn't answer properly, blabbered just something in a sign of no, and stood up.

All the way I was thinking i had done something good, all the more so when I was feeling a bit tired, as the journey took more than 45 minutes I think. But I do not know what and why I was thinking when I was sitting.

But later, when I was standing there was one question in my mind. Why do we think so much while we do some good work?

PS: I would also like to know if you have the same thing applicable to yourself. Please tell if it is so. And if you find any reasons for that, what they are. Thanks.
