Like the movie liar liar.

Why can't you just have a day to make a wish that a loved one can't lie for a day. How heartbroken do you have to be to make that wish come true. Do you think it come to a sweet ending with that loved one realizing just how wrong they have been and actually have to admit what they have really done. Or do you think it would totally destroy things? Maybe the truth would put my mind at ease.
