<human>: When we've been alone (literally 4 times), it seems we get along just fine (probably because I'm the only option for her to talk to). In a group, when she turns up (or I do) she says "Hey [MyName]" really upbeat and when she goes (or I do) says "Bye [MyName]" in the same way (If I'm new to the group or the first one she sees, i.e. she doesn't single me out from groups). But never actually says anything to me the rest of the evening/lecture/whatever we have.

She talks to everyone else. I used to talk to her after she said her initial hello, but lately I've just stopped because I don't think it's worth my effort if she's never going to. I barely say anything when there are a group of people as well as the first commenter, in fact I'm horrendously socially awkward. She's really not at all.

I guess we're not really friends. Should I just start ignoring her when she hello and bye? It seems like that would be best.

I know this seems really childish or some word of that ilk, but being a social tragedy I'm not really sure what to do.

Summarize the given text in a few sentences.
<bot>: Friend says hello happily then ignores me for all activities. Should I just ignore everything to do with her? She's not shy at all.
