There is this saying that "friends don't lie" I grow up believing this idea, I believe friendship is all built on trust, loyalty. As a child, friendship was so sweet and smooth,no compromise and complications,pure and genuine love, I was brought up with love with my sister who are my first friends,so I believe so much that every other person are just like my sister then, I felt free and relaxed, then as a child we becomes friend the day we meet, once we become close we are honest to each other, we keep secret at each other's hand.
We all started that way but as we grow older , friendship becomes more complex, priority changes, jealousy got involved, we started to do competition among ourselves,what we started to chase and look after started changing the concept we have about friendship, during this stage we realize that the phrase "friends don't lie " can be questioned. To me, it's not a yes or no answer because of the experience I have had with the little years I have been on earth. Friends are human,human are bound to have flaws, friends lie but not all lie are to hurt.
There are some situations that friends lie to end a fight, some are to protect their friends from being hurt while some lie just to be your friend maybe you have something they want or need , some lie for their own selfishness while some lie not to put burden on their friends like saying " I am fine" when he/she isn't fine. Not every lie is intentional, thought I'm not stating the fact that because it's not intentional doesn't mean it's good to lie but we have learn that the weight of lies are different, a protective lie is different from a manipulative lie.
If they would take blame for their wrong,if they admit their mistakes,then that's true friendship, because they knew they shouldn't have lied and wanted to build that trust back. There are some situations we find ourselves that we can tell truth,this adulthood has taught me that all friends needs your honesty, not everyone. They are casual friends,a neighbor that you are not stronger nor too close, and the real genuine ones, I had to distinguish between them for my own piece of mind.
Honesty is the foundation of every good friendship and learning to speak the truth even when it's difficult should be embraced.
