I think that every siituation has it's own reason and result. Because of it, from my opinion, we should tell the truth for our children. But, of cours it depends on age of our children. If the child is in the age of 5-13 we should explain every thing, perhaps in other way, more softer than it actually is.If the child is in the age of 13-18 we, I think, must tell the truth, because in this age they need the truth, we can see that sometimes they claim the truth from people around their. They are very severity to lie. And every child has individual character. Some people take something easy, some people have problems after that. Also I want to say that many things depend on character and, of course, situation. And every person must peruse his action and then  decide  to tell the truth or lie.
