“Tell the truth, or someone will tell it for you.” 
― Stephanie Klein

The truth will always come out, even if it's something you think will never come out. It's better to be truthful than to tell a big fat lie, because then when the truth does come put your going to be labeled as a liar. Even if you might feel like the right thing is to tell a lie, but usually when you lie, you have to tell another on top of that. Which will cause more stress on you, and end up getting caught up forgetting what lies you told. You'll eventually get caught and then there will be no trust, and without trust then there's nothing. That's just how I see things. No one likes someone who's not honest and doesn't like to tell the truth.
