How can I reopen with a girl I talked to once, but never did again?

Long story short, this girl I had a short conversation with (that didn't necessarily go well, little/no kino, didn't number close, heck we didn't even exchange names) I now see frequently waiting by the bus stop/ on the bus. But, I never said hi again after our first conversation.
How do I reopen with her?
Any advice?

She's not important to me, I'd just rather talk to her than wait at the bus stop silently a few feet away from each other.

Were both pretty young (Highschool) if that changes any factors.

I would just make eye contact/smile, and say hey/hi, and try to start a conversation but theres one major problem with that:

She kind of avoids eye contact (but I bet that's to avoid awkwardness/ hope I don't recognize her <I assume it's that because It seems like something I would have done if I didn't know the stuff I learned from PUA.>)

what about...

hey how is it going? what are you doing?

Been there, done that. I recommend using an opinion opener. Since I'm guessing this is in the morning act like you slept on the decision but you still couldn't get an answer. So you need her honest thoughts on the matter.

eventually, you'll have to neg this girl at some point just because of the time she spent not talking to you. But try to remember what you said to her the first time and post it here, so we can get a better idea of where exactly you stand with this girl.

I'm highschool and I heard negging younger girls isn't a good idea. But yeah the conversation wasn't that long and pretty casual, we were talking about gym and volleyball. I didnt do any kino though.

its so easy to misinturpret negs. Negs are meant to put you and your target on the same ground once you have rapport built. For example, she may think youre funny but unless your value is equal to or higher to hers, high school or not youre in the ljbf zone. A neg would say "hey, im just as cool as you are maybe cooler."

People that point out harsh, almost insulting things are doing it wrong. A true neg is subtle, something like *did you know your nose wiggles when you laugh, its so cute* thats it.

Usually in high school and most school settings its about social circle gaming, but since youre just at a bus stop its about striking up a good conversation and you couldn't ask for a more isolated target.

Btw you need kino if youre trying to escalate. If you plan on eventually going somewhere with this girl then go ahead and throw in some light touching when the convo reaches a high point.
