In fiction writing, the phrase has been extended to refer a sudden and unexpected resolution to a seemingly intractable problem in a plotline.[2] A deus ex machina is generally undesirable in writing because it does not pay due regard to the story's internal logic and is often so unlikely that it challenges suspension of disbelief, allowing the author to conclude the story with an unlikely, though more palatable, ending.

I am not into pet names in RL too. I call people by their whole names I don't usually even shorten them. And it has no relation to my love for them.
