No one always talk honestly. Everyone must ever lied, both to protect themselves and protect others. Lies are not good. It's different if we say lies to protect someone who is innocent. These kinds of lies are certainly different from lies that are deliberately done to hide mistakes or other things.
Lies can cause a broken relationship, be it bloodshed, friendship or love relationships. Trust will disappear and can even have a worse impact. For example, when someone is deceived, then he will demand revenge for your lies by way of injuring you.
Beware of lies
People who lie will usually immediately refuse to be blamed, even they will not say that is their fault. Liars will usually try to explain why they act in certain ways when no one asks them why. They use too much detail, or they speak in short phrases to hide the truth.
