<human>: So I have a paper to writewith a teammate from the class that I wouldn't really describe as a friend, the closest we got to friends is walk together after class if we're headed the same way.

So we had planned to meet in the lab to work on our paper, and she came late (a friend told me because she had an argument with her boyfriend, but I didn't really pay attention to it) After about to hours her boyfriend comes in and tells her to go somewhere with him as they planned and she seemed to be really upset with him but for some reason she decided she'll go anyway. She left the lab before he did and on her way out she leaned in and kissed me goodbye. I saw him right after she did and he didn't seem very comfortable.

Is this weird? Or is it just some normal thing that people do? 

To clarify, I live in Morocco,a nd kissing you close friends in the cheek is pretty common here, the boyfriend is an American exchange student,a nd the girl and I are Moroccan

Give me a shortened version of the text
<bot>: Not-so-close fiend kissed me in front of her boyfriend and I feel like she did it to get back at him.
