one word, guts.
how many times you saw a chio bu on street and you dare to
approach her?
if your answer is zero, then you should know you sldn't be
whinning.
in fact, most gers are honoured by the fact that any random guy
on the street would want to know them. be it whether they are
interested in that guy or not.
a simple "hello" can already start a very simple conversation
with a girl.
