Or you can talk her about Kaczynski.For example ''Kaczynski seems to me rather sexy.''
She will be suprised and say:NOOOO
I don't know why I should show that I don't care for her when I do though, playing games isn't my kind of thing.
It is direct vs indirect.Some men like direct,some prefer indirect.
For direct you need right body language,good tonality,eye contact and a lot of things.It is difficult to achieve.So you go indirect.
If you show you are not so attracted,it means that you have independance,you do not fall for her so quickly,you are not easy to get,and this creates attraction in women's mind.For example when will you be more attracted to agirl?If she sleeps with you from first date or if you chase her for some time?(I do not give here advise to girls).
