ohh us poor asians are always cursed with the shyness gene... maybe it's coz our parents (the more... err.. traditional ones) lock us up at home and make us study?? hmm... that's besides the point... aAnyways
like someone said before, just go talk to the girl hahaha you might feel kinda awkward talking to a girl for no reason (i used to get that alot =( ) but it's not really that hard is it? even just catching them in the eye and smiling is enough to start a conversation =) lol why not just go up to them and say "hi, it's a nice day isn't it?" LOL so yeh... and pick up lines are pretty overrated, in fact, i don't think there's such thing =___=, just go say hi
you don't have anything to lose (and everything to gain) by saying hi
hope it helps you dude.
>.> now i gotta go find myself a gf >< HAHAHA xD god... aren't we all on the same boat? LOL
