To me this is just so sad. With a bit of empathy you can actually tell them that you are busy or not in the mood. It only gets awkward because or if you try saying it without saying it, if you show them you feel uncomfortable (in what could be a completely natural interaction between people in the same group who spend a significant amount of time around each other). The other person probably feels a bit lonely if they try to find somebody to talk to repeatedly. Of course, the direct approach works best if there actually is empathy, in the story here the only feeling shown for the other person is a pretty negative one.
