The word trust is a really strong word not many people seem to know what it actually means.
well it basically means that the person you decided to trust you can tell them absolutely anything that you want them know and WON'T tell anyone unless they think it's really necessary to do so, but i still think they should go and talk about it with the person they're concerned about before they go of and tell someone that the other person might not even trust and before they know it what they told the person is not private anymore.
so basically what i am trying to say is to be careful on to who you trust because you might think that you can trust them, but you couldn't be more wrong. so think it through carefully on who you are going to trust!
