The truth or to feel good?

Sometimes we are in situations that make us take a very hard decision: Tell the truth or to feeling good.

Sincerely I always think that it's better tell the truth that make false ilussions, Maybe truth can hurt, but time can heal that pain, and after a time we can accept the truth.

However in some situations we can blend the truth with the feel good, for example when a doctor has to comunicate to a pacient that he has a deadly disease, or when someone tries to breakup with his girlfriend or boyfriend; in that situations we tell the truth, but inmediately we say something to cheer up or to make feel good to the other person.

But it always there is an exception, when we have to tell something to make feel good, or tell lies. A distinct example is when a mother, or sister, or girlfriend put a horrible dress, and she ask to us "do I look fat?" we don't have any other choice, we have to say that she looks great.

I think that maybe sometimes we could tell a "white lie".
