People and behind them

You know, We won't like it if people talk bad behind us.
But you know at least a group of people most likely wouldn't talk that bad about you, when that group of people talk bad about others with you.

It seems that when they are talking bad about other people when you are around, they have some trust on you. With that trust, they trust you not to tell the people being talked bad about. With that trust, you unconsciously trust that you won't be talked bad.

But we'd never know, do we?

I might think myself is already nice enough, but again, if people talk bad about me I shall not know.

But it's okay.

But suddenly I feel bad about talking bad on other people's back.
Though sometimes it seems like they indeed deserve being talked bad on because everyone just talk about that particular person, and it's because of his/her own attitude.

I wonder if I'm like that OR I'm already like that, and I don't know what's happening, what will I do? Just stand there with the naive thinking that I'm okay with everyone when everyone's not.

This is a bit paranoid, but these days, I think I talk bad about people so much.
I talk them on daily conversations and on this blog.
Again, so, If you are able to read these posts of mine, you are so called "given the trust" by me as mentioned above.

Should we just let this be because this is already how the way it goes?
Do we really need to talk bad about people?
Or can't it be helped since the people we are talking bad about are indeed so bad that we can't help not to talk it?

Tsk.. Cruel Society, but people should grow up!
