Dangerous Lie...

What can we say about lie? It's not easy to explain. But I'll try.
On the one hand it's bad, but on the other hand, it may help you in dangerous situation.

Someone people lie in both situations. Of course, it's not true. If you need to lie, you may do that. But there are many people who lie only just like that. To know, lie people to you or not, it's difficult. It may end very bad for people, if you lie them only just like that. So, people must lie a bit, especially only just like that.
