Just a fun conjecture, based on this fascinating article. It sounds plausible to me, because what *else* could explain her (and Robin's) seeming need to start arguments, start "shooting" at the other parties in the arguments, and then strive to keep the arguments going as long as they possibly can. There must be a "payoff" for them in this. Maybe it's the "flow" this person writes about.
