Cool eh? I don't ride bikes but still, it doesn't stop me from
looking and admiring. 
Hmm.......kopio.......sometimes we don't know why people behave the
way they behave. Unless you ask her bah. We guess, guess then
sekali is not what we guessed. Then, break or spoil the
friendship.........wasted, right?
So, if you value her as a friend or thinks she can be a good
friend, you ask her lah.
But if she dao dao like that, then forget it lah. If you like
someone and she likes you back.........this is yuen fen already. If
she makes it difficult, then (1) she likes that kind of
feeling.........being pursued or (2) she is not interest and it is
a subtle hint liao.
