Do you think that there are cases in which we must lie? Or should we say truth always? Do you agree with statement "Everybody lies"?
Yes, I think there are a lot of cases when it is better to lie partly or even fully. I'm against of lie about very important or principal questions, but if the question isn't very important nothing change if you try to say your opinion in more polite words and not as straight as you can do it. For example, when your very close friend or even your husband or wife ask you did you like her or his parents and honestly you didn't, of course, you can say: "No, I think that they are very strange people with stupid habits, have strange outlook on life and behave themselves absolutely irrationally. I don't want to communicate with them anymore". But if you say, for example: "I think, that they are quite usual people, of course, as all with strangeness, but it's doesn't matter because for me did I like them or not because I like you and I'll try to get on with them". In this statement you even don't straightly lie, you only don't say how much you didn't like them.But I think, that it is a type of lie.
However I don't think that there are cases when you MUST lie. You always can say the truth. Another question is: "Is it better to lie?" And sometimes it is.
I also agree with the statement "Everybody lies". Someone lies every hour, someone once a year, but there is no a man in the Earth who never lies. I really assure in this.
