If she's a classmate or a co warker then always greet her and ask her how she's doing. Ask her what kind of movies or music she likes. If she's someone you don't really know then start a coversation that's neutral like the weather or something like that and just try to lengthen the conversation and let her know that you are really interested in what she has to say. That always works for me :-)
