When Bill Nighy asked Sheba 'WHY!!!!???'
(Possible spoiler) As in WHY did you do it w/ the 15 year old vs. (as he put it), the conventional way, cheat w/ an adult? I sort of have the same question. Hear me out:
I do not believe the answer is "because she is a pedophile". But, really, truly, underneath all the possible superficial reasons (the attraction of a youthful body), WHY did she say yes to the kid?
Do you think she basically "missed" her own youth by marrying so young? (in the movie, it was said they met when Sheba was 20, and obviously, kids soon after). And as she said, felt "entitled" to be "bad"?
She seemed to genuinely love and care for her husband; they didn't show any arguing or distance or anything that would indicate a problem in the marriage, i.e. so that we, the audience would know she was vulnerable to an affair. But that wasn't the case.
Although Barbara was a total misanthrope, and ALL her observations were bitter, she was spot on w/ what she noticed. And she knew that Sheba's marriage was not working, but Sheba never owned up to that.
So...comments? Theories?
