Currently (and not so currently), I've become such an observant.
There are bad and conniving people who always manage to survive and manipulate with their loudness and their convincing making-up stories skill. And the sadder part is, people around would always buy it, without questions.
Of course, people will always tend to believe in something which properly and dramatically made-up, than just a simple plain truth.
But in the end, it's always about karma. What goes around comes around.
Whatever things you did to people, it will always get back to you.
