It depends on the reason of the lie.
If the purpose of the lie is kind,I accept and forgive a liar.
For example, a girl shows off her new hair. But, the other friend thinks it is ugly.
In this case, If a friend being honest, a girl could get hurt.
A friend would say pretty, and a girl feel[s] great.
But, If a person lie[s] with bad intention, I don't = wont forgive him/her.
