It can mean many things. For example, she is crazy and says hi to everything, not excluding inanimate objects. Or you lost your memory and she is really your long lost sister. Basically, unless you were to provide more information about this phenomenon that could be used to develop a reasonable hypothesis, there is no real way to know the answer to your question. But, assuming you are both completely normal and unexciting people, there are a few logical possible explanations. First, she likes you and wants to be friends. Second, she is simply more social then you and greets people she doesn't know so she will cease to be surrounded by strangers her whole life. Third, you met her once and forgot her but she didn't forget you. Lastly, she's messing with you for fun, trying to unsettle you for her own personal amusement. Anyway, I recommend you say hi back and ask her name. Problem solved.
If you are trying to talk to a girl and she keeps saying, "Bye, I have a boyfriend," she probably isn't interested. She is letting you know that she doesn't want to talk to you. There's other girls out there.
You cant "make" somebody like you but you can be attractive enough for them to like you sexually without you knowing.
Stop it.
ask her
You should not kiss someone without them knowing or without them wanting it. Plain and simple.
Some do, with or without knowing the orientation of the male.
she likes you but she doesnt know how to represent it
Yea she likes you a lot or she's obsessed.
you don't have to annoy a girl if there is no good reason for that , but if there is ..... well that depends on what tipe is that girl , and if you know her well you should be knowing how to do that
