T.R.U.S.T.
I used to trust people easily. Whatever people said, I'll just trust them without thinking if they were lying to me or are they trying to make me a fool. And that was what I used to be.
As I grow older, situation changed. Whatever people said, I think twice. The fact is that, I learnt from my mistake judgments. People who lied to me, betrayed or maybe just simply I don't trust, be it my family members or friends, as long as he/she is a human being on Earth, you misuse the trust I given to you, you can't blame me for not trusting you.

Trust is easy to be said. "I trusted you.", "You're the only one I trusted.", "trust me."..
But things are much more complicated than what you can even say. It might just turns out to be "I trusted you so much and you did this to me!". Seriously, I'm sick and tired of saying this sentence over and over again. Not to people in the face, but when I'm all alone thinking about it.

"Once bitten, twice shy."
People who get hurt once, you think the next time they will not be careful than usual? Think about it.
And this is the reason why you don't get the trust from them.
When a glass break, no matter how hard you try to fix it back, there will still be crack on it. Pain and hurt had already cause them to beware of whatever they trust.

Next time when you are going to do something which will lead one to not trust in you again, think about what are the consequences. Don't wait till the day when they found out that you had been lying to them, and then you start pointing fingers at them. Saying that you had done so much and they don't trust in you. It's you who ruined the trust between he/she and you.
And.. This is not what they wanted to behave like.
