Why we are like this?

This is the observation which i have been doing for very long time especially in India

1. Please scream only there is a problem for them alone
2. Don't care attitude if something is happening to others.
3. Unprofessional attitude by the people who seems to be highly educated and employed in good companies.
To get the actual picture, i have an incident by which i can explain this particular one very clear. We were standing in the food court for taking the food in our plates, when our turn came, me and my colleague started putting the food in our plates. All of a sudden, a hand pushed us apart as we are standing close to each other. Then only we realised that the guy is also trying to take food jumping the lines. I have a question for him. If you are so urgent in doing things, why can't you ask the people to leave some space for him.
This sort of attitude is everywhere and i believe we have gotten these things by birth itself.
We can do some research and then find which part of DNA is making this impulse!!!
I believe i have created a new area of research for the Indian Doctors!!!!!
4. Being silent makes people to think that the person is useless

Though i have seen lot of good things in people here, the above points constantly hurt me....

(I believe i wrote this 3 years back and still valid and thinking why this was not posted?)
