what rauakbar said and just the form factor . the 4000100 black is 3 . 5 and 4000400 black is 2 . 5 . otherwise both seem the same . <| sep |> This isn ' t exactly a straight girl thing . This is just a shitty person thing . She knows she has your attention and taking advantage of it because she can . I truly don ' t believe you can be friends with someone who you have a strong attraction to . Every little thing she does you will take it as a sign . I would say give yourself breathing room and just be very start up with her . I was infatuated with an older lesbian . I suppose she enjoyed the attention and also we actually did get along super well . But she had no interest in me beyond gentle flirtation at best . Just shut me out of her life one day . It was hard lesson to learn and accept . And I was on the other side of a friend ' s crush on me . Even though I never flirted or even remotely suggest any physical interest . It ' s hard because you enjoy their community and then you just ignore the awkward moments . She takes it as you are game for it . Then obviously things will implode at some point . And I do wish I made myself more clear , I always complained about other girls to her , or mentioned if I was interested in someone . Anyways we don ' t talk anymore .
