The only time I find it hard to speak the truth is when the truth will hurt someone. I will go out of my way to "gloss" over the hurtful part. Sometimes depending on the situation, I do not tell the person the truth because I feel the "hurt" outweighs the truth. If nothing good can be accomplished when that person knows the truth, then why hurt them. If someone is insistent on knowing the truth about a situation, I will tell them though.
