Sleepy Patrick is indeed adorable, as is concerned and shy Wiley. And yes Kara is scary, but in that sense that you just don't know what she's truly capable of but you know whatever it is, it's gonna hurt like a bitch.
I actually don't get, why Kara is perceived as scary. Maybe because I can relate to her a lot - but yeah, why is she scary? Please, do tell.
Also: your comic inspired me to try wearing tanktops without a bra - it feels great :D
Why is Kara scary? well, she is a distant person that only seem to get from her clouds when she "wants" something. She doesn´t seem to have any problems of her own, and gets away from trouble, which seem only to happen to people around her. I think that is why people like Michelle don´t get along with her (at least on first sight), since people that want to give the impression of not having problems just look like hipocrites to her, even through she may be just a normal girl. Maybe that why she needs Peter, it must be lonely for her.
