Ahh, little bro does not have time for her mood.
To be fair, though, she’s just been through a pretty bad breakup. So, I do have some sympathy for her. Sometimes, you don’t want to put on a brave face and pretend to have fun when you actually feel crappy. The only thing about her case is that she’s usually so blind to other people’s feelings, that I can see why someone who isn’t particularly interested in her as a friend or family member would be put off by her behavior. I mean, her whole family basically rearranged their schedule to try to take care of her. It’s a bit excessive.
Also, I wonder how he’d react if he knew about how her ex harassed his sister for the longest.
