there is three kind of people in this world,
highest level one is expensive people,
medium level one is cheap people,
lowest level one is free people!
what is free people?!
once upon a time,
there were eight friends,
they used to yamcha every weekend,
after quite some times they didnt meet each other,
one day someone suggested to yamcha so he informed everyone,
two out of that eight person suggested watch movie before yamcha,
why?! because they already planned to go watch movie themselve!
so they sun bian ajak the rest when they got the yamcha message!
if didnt planned to yamcha noone will even know that they are free!
and the conclusion is that two person is considered as free people!
lelong! lelong! lelong! buy one free one!
