So I asked someone I was interested in out to lunch yesterday, but didn't determine a time/place (I believe I suggested Saturday.) Later that night I called her to set a time and place, but she didn't pick up, and I left a message asking her to call me back.
Maybe I am wrong, but is it safe to assume if she simply never calls me back, well... shes not interested, and that's that? I coullld be more proactive and try calling her again tonight, but I think that would seem like I was acting a little desperate, am I wrong?
