'Sarah' nicely reinforces flaky ho-slut-puppy (+tattoos) archetype, lol.

i.e. 'Winston' treats her like a bar-fly he don't care squat about, and she gives it up THAT NIGHT--for a cigarette! And not in a drunken or hesitant or didn't-really-mean-to way either, but in a HOP ON TOP, do NOT bother undressing, and RIDE THAT COWBOY--YEEhaw! girl, get YOUR orgasm TO GO, and let Him worry 'bout Him! LMAO!

OTOH, 'Rand' plays Duh White Knight, he puts her on the proverbial pedestal, and she leads him on for weeks/months, doing all those "couples" activities, always manipulating his thoughts until his words are what her soap-opera meme is comfortable hearing. When he FINALLY does plow her field, the wild rodeo cowgirl is gone, and she's all lame and passive, and can't muster the Kegel pressure to cross Rand's dopamine threshold... pity.

Both Winston and Rand got used, but at least Winston enjoyed it, without having to sublet his whole life and worldview to pay for her past mistakes.

Girls like 'Sarah' are why lounges and nightclubs will NEVER go out of biz... nor even slow down during recessions! ;')
