1) agree with daisuke, no reason to call
2) no. if im the guy, i would think that the gal is avoiding
me.
3) yes, the guy is interested in the gal
4) not too sure, u can check with the scientist.
but sometimes hor, number 2, the girl might really have
something on.
so I usually give her the 3 choices before letting her
answer
" Yeah Sure", "No I'm not interested" & "I have something on
that day, how about another?"
