While I understand your frustration, I do think that you should not be upset. After all, your wife isn’t smiling about “some guy” — Jacob, in his full shirtless awesomeness, isn’t explored until the second book, and there’s no way Maria is smiling in such blissful fashion over the vampire. Her taste is better than to settle for Edward.
Maria is most likely smiling over the syrupy sweet romanticism which is ever-present in the book since, after all, its target audience is teenaged girls. (Note: while I say the books were written for said girls, obviously they’ve also found a much broader fan base. Syrupy romanticism, it seems, can be enjoyed by most girls, regardless of age.)
Getting back to the point, you, Dan, could possibly get your wife to smile in similar fashion — actually for you though! — by performing a gesture which would be considered by a 14-year-old girl to be “sooo sweet!!!”. Or alternately, to turn into a shirtless teenaged werewolf. I suspect that the smile then would be a slightly different one though.
p.s. If it turns out that Maria is, against all common sense or rationality, #TeamEdward, please tell her to return the books by mail when she’s done and that I’m sorry but we need to break up. (It’s not her or her cakes, but it’s not me either. It’s her terrible taste in supernatural boyfriends.)
There is just no condoning choosing a creepy, century-old undead monstrosity over a devoted, warm-blooded, virile werewolf of one’s own age. There just isn’t.
