Is it someone who soothes your pain with little white lies? etc etc. (Feel free to use this as a start off point)

On the other hand, if it is a story then you will need to think about things that you might see as negative, which ultimately turn out to be a positive. So you have a beginning and an end. The beginning of the story should introduce your characters then move on to the bad thing that happens, the middle should overcome some kind of hurdle, and it should end in the realization that whatever happened was a blessing in disguise.

Hope this helps

Draw deep inside yourself…

You will find the answer.
