How do you flirt with a girl without being obvious?

plz help i really like her i just dont know how to approach herHow do you flirt with a girl without being obvious?
talk to her like shes a boy like you, if you talk to her like you talk to your mates you will come across friendly and confident rather than nervous and asking stupid questions to get yourself noticed, theres only a certain amount of times you can say ''nice weather were having'' without coming over as a jerkHow do you flirt with a girl without being obvious?
it depends on girl.

just talk to her and do whatever she wants, but don't be pathetic. that's the only thing most of the girls can't forgive. :D

good luck.
well you now she is aventualy going to find out you like her by somewone else so its better to just be honest
the best chat up line is can you cook. If she say's no ask her to try walkers crisps if she say yes that's a sine of your pulled and she likes you by talking back to you try it ?.
Just be a gentleman. Invite her for a drink or even less obvious, to a party or a club with some of your friends, show her some fun and you'll see that could work.
