Yeah, it happens for pretty much the same reason. It's because I'm an overthinker, and debates and arguments (especially arguments) tend to cause me to overthink more than anything else, such as the feelings of others, their feelings towards me, their state of mind, if I should have phrased things less/more aggressively, etc., even when I know it's not personal.
It's pretty ironic, 'cause I've always held firm in the belief of not caring what other people think. I guess that form of thought and my overthinking habits contradict each other -.-'
Kraus would probably meet her with crude indifference or callous friendliness. The fight wasn't particularly long, and it gradually moved away from the group, so chances are she wouldn't have much time to help him out, or if she did, there wouldn't be much to be done.
It's less that and more the fact that I do not have a high opinion of monogamy and Valentines Day tends to result in the rest of the world reminding me how arbitrarily locked out of their upper friend zone I am.
