Why do people..

Agreed. Another thing to add is: All of us should look at ourselves first before criticizing about other people behaviours.

Something aside: Another thing I have noticed here recently is that we boast about how we respect our parents and elders. Yet, on the other hand, we complain about our FILs MILs on online forums. Especially the way women/girls come up and talk about them. I bet they would not say the same for their own parents no matter how annoying they might be. Anyway this is just an example.

Nonetheless, our self-centered behaviour is one of the disturbing reasons we are a third world country.
