A definition of drama, as illustrated by one who engages in drama--an example from one of my own encounters:
Let's call her Tami. Tami had a fuck-buddy who she hated. Her fuck buddy got her pregnant.
Tami found out I was gay. At that moment she decided she may also be gay. She didn't like oral with women though. In fact, she didn't really like making out either. She just liked saying she might be gay.
Offenses, such as accidentally bumping into her on a dance floor, were met with physical violence. "She started it!" she would yell as she was being dragged out of the door by bouncers.
Tami met a woman who'd been treated for cancer, and made fast friends with her. It was at that time Tami decided that she'd been treated for cancer also. It was never clear what type of cancer Tami had been treated for. Tami just wanted "Heidi" to know that she had no reason to be concerned about her ovaries being fried by chemotherapy because Tami's had made a full recovery (witness her newborn from her fuck-buddy).
Tami alienated a lot of people around her, became enraged at their rejection, and went into hibernation for about a year. She appeared out one night, enormously bloated from overeating and drug use. She wanted everyone to know that the weight gain was likely a holdover condition of her cancer, which, she theorized, had messed with her thyroid. She did not confirm whether or not she'd had thyroid cancer, nor did she indicate it was from a return of tumors during her year of absence. We should just not be shocked by it (not that anyone made mention of it).
In summary: Tami is a drama queen. Some actual unfortunate events (perhaps the unnamed cancer) had combined with manufactured or irresponsibly acquired circumstances to make most of her life miserable, and she seemed to really like it...in that no attempts were ever made to learn from each experience to avoid similar pitfalls. Not incarceration, loss of jobs, electricity or heat, nor the eventual pregnancy of her teenage daughter--nothing--would stop her participation in an obviously foolhardy choice.
What makes her life drama is not in the happening of the circumstance, it's in the joy of recounting the experience, as though it was some gift to the listener.
