These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Did Zoey deserve all of the things done to her by Larisa, or is Larisa just being an outright bully to her and she's just a Jerkass Woobie?
When Michelle rejected Zoey's affections after her sudden kiss, was her reaction just trying to remain calm and in control of the situation, or was she just painfullyOblivious to Love?
Her reaction that night lends itself more to the former idea.
Michelle's huge Oh, Crap face at the end of Zoey's arc, has spawned quite a few theories from Zoey being a Closet Key, to Michelle becoming a Heteronormative Crusader. But judging by the later strips (using the homophobia of Landon's mom to get her to allow Landon dating Larisa), she was most likely shocked of how she hurt her friend's feelings. It is also a educated guess, that she apologized to her.
Broken Base: The political references and humor of certain strips (which date back to 2009), as well as the more controversial story arcs (such as the Dorothy Cambridge arc in mid-2014) and the gradual decrease of focus in the title characters (who seldomly appear together in the same strip nowadays), have caused a Vocal Minority of readers to stop following the comic, but is still popular among many other readers who don't take offense at the aforementioned things.
Because of differing viewpoints on the nudity taboo, this strip passed in Germany without much issue, but in English-speaking countries, got Knörzer and Powree briefly accused of playing an 11-year-old up for fanservice.
Larisa accusing a teacher of having an affair with her in order to get out of homework strays into this territory. Such accusations can cause a lot of trouble for a teacher, even if they're blatantly untrue.
According to this, fan interest in Zoey went up a lot when she was confirmed to be a lesbian, with an unrequited crush, to boot.
Michelle as well has garnered a fanbase, most likely helped by her pulling a Crowning Moment of Awesome to help along Larisa and Landon's relationship.
Joe Miller only appeared in two strips, but because of the funny (and heartwarming) twist at the end of his arc, quite a few want to see him return. See the strip and the comments here.
"Funny Aneurysm" Moment: This strip which isn't as funny when you realize that Woo hasn't appeared as much since Sandra and Cloud became a couple. However, Sandra still likes being with Woo and spends time with him, so it isn't as terrible.
Armin Fish counts because of what he wanted to do. It's not quite as bad as what it makes you think at first, but still very inhumane.
Although with what she has seen of Larisa, Landon's religious mother has at least some justification for disliking Larisa and not wanting her son to see her...but then she sees her son with a painting given to him by Larisa for his birthday that she does not like, and proceeds to deliberately destroy the painting and threaten to beat her son if he ever sees Larisa again. She apparently backs down on this after Michelle tells her that Landon was actually gay until he began dating Larisa.
Landon's mom, Harriet, for being the embodiment of everything people hate about Fundamentalist Christians.
Dorothy Cambridge, the biology teacher that appeared for an eight-strip-long story arc in 2014 did not win anybody over either, especially with her poor treatment of Cloud. She is probably the most-hated character on the comic's history. You can see the strip (and the comments below)here..
Despite the characters' ages, there was a Love Triangle among Sandra, Cloud and Larisa early in the comic, until Cloud chose Sandra and Larisa started a relationship with Landon.
They are careful to depict the relationships of the main human cast (and their peers) in an age-appropriate fashion. Relationships are strongly suggested never to go beyond french-kissing, and even Larisa, who is depicted as being rather... er, precocious, is probably not going to do anything beyond that, since keeping her virginity is her mother's only concern. By this strip, however, is apparent that Larisa wouldn't mind actually taking the "next step" with Landon, but he is clearly not ready.
The principal for taking away Larisa's insulin shots. This is hammered home when she explains that she needs them to live, and the principal interprets this as dependency. Lampshaded when Larisa proceeds to repeatedly hit her head against the desk.
Dominic in "The T Word". What do you say when your dad is caught by airport security carrying a squirrel in his luggage (albeit by accident?) Why, claim that it's a TERROR squirrel trained to attack, of course! *facepalm*
Dorothy practising sexism towards the male students in the school is this. Potential for lawsuits and losing her job aside (which adds to the principal's own score for hiring her and allowing her shenanigans to take effect despite this to begin with,) consider one of the students she had purposely screwed over. As many of the comments pointed out here, consider who his mother is. Sureenough....
Write What You Know: The writer of Sandra and Woo is very interested in raccoons and wrote several Wikipedia articles about the species. He was also the creator of the Wikipedia article about the comic.
Woolseyism: After comparing the German and English text, it is safe to assume, that most, if not all of the text is written initially in English and then translated into German (sometimes the cultural references, slang and word plays can be translated, sometimes not (both the ones in the text or sometimes even those drawn ones).
