Who should we trust?

Our parents taught us never be a liar when we was young. However, most of us did. Nobody wants to be cheated deceived, because that feeling hurts and I totally understand it. While the society becomes more and more fascinated, people learned how to get what they want through telling the lies. And yet most of people are keep doing it even though they know hat they are wrong.

There's a saying says that the person who ever lied should sallow 1000 needles. It's pretty creepy isn't it? I think that nobody really wanted to be a bad person or saying fake stuff; I think everyone wants to be a kind person. But what turns them into this?

Temptations.......................

For example, if a boy wants an laptop, he would thinks about all kinds of methods to get it. First, he would begging his mom, if his mom agreed, then he will be happy but he might become greedy and wants an speaker to go with it. However, if his mom refuses him, he might makes all kinds of lies to persuade her.
If there's no computer, then this boy won't be lying to his mother. But its impossible to remove all those temptations from nowadays society, so the only way to avoid it is to change ourselves.
