Why do people invite others to things if they don't want them to go?
My roommate invited me to hang out with her and her friends because they were going to watch the sequel to a movie (after they had watched the first in our room and invited me to watch with them) a few days ago, however last night they watched it in a different dorms lounge and though she told me she was going to text me when they were going to, she never did. I understand we don't have to be close as roommates, but my question is why even bother inviting me if she didn't want me to go? Was it just an obligatory polite invitation that she didn't expect me to accept? I genuinely don't understand.
