See, this is the reason I keep going back and forth on how I feel about Brun.
On the one hand, she is an interesting character and can be quite likeable. And I can definitely sympathize with anyone who has trouble interacting with people. I may not struggle to the EXTENT that she apparently does, but I've been there.
On the other hand... I know it's partly for the sake of the last-panel joke, but the very matter-of-fact way she rejects a joke that does not fit what it *should* be kinda annoys me. I guess that speaks to the way her train of thought just goes to places I do not comprehend, but a person who has trouble communicating with people acting like there is a proper way to respond to what she said is something that just rubs me the wrong way. Upon rereading the comic, she doesn't say anything angry or negative, and she seems more baffled than anything judging from her expression (I think it's Clinton's "Sorry" that threw me off), but her reaction is just so off-the-wall, it makes no sense to me that she'd act this way, no matter how fixated she is on dog jokes at the moment. Plus, maybe it's where the comic cuts off. Clinton's "sorry" and a lack of further speech balloons from her seems like she thinks the "sorry" is warranted. If the next strip continues this particular thread of conversation between them, my perception of Brun's reaction might completely change.
Right now, though, how shall I put it... in many situations in my life, I share Clinton's attitude of being overly apologetic. So I have a lot of sympathy for him, especially since he didn't do anything wrong. And my sympathy/empathy for him right now kinda translates into being annoyed at Brun, I guess.
It doesn't help that her jokes are... I'm not gonna say "terrible", because I actually love groan-worthy puns. I honestly do. But they seem super-forced to me, they barely make sense as puns. Although I'll admit, they're very "Brun", I think. She seems to mash two words that kinda have a similar element together for a pun, I somehow think it's very in-character for her to take this very... methodical approach to joking. Doesn't change the fact that I still don't like the jokes.
Or maybe it's just that I don't like characters that act extremely, for the lack of a better word, wacky. Emily is consistently my least favourite character, so maybe there's just something about characters not reacting "normal" that throws me off.
I'm sure I had a point in there somewhere, but seems I've gone into disjointed, random comments on the comic; sorry about that. Hopefully part of my comment is somewhat useful or insightful to someone in some way.
