How do I woo a girl if I dont even know she likes me?

It might be a good idea to find out (by asking friends) if she wants to be woo'd by you or anyone. Then just be yourself! Let her learn to like the real you.

You can woo people even if they don't like you, just don't do it over and over cause they might get the wrong idea if they don't like you. But if you do woo someone that doesn't like you, be careful cause (worst case scenario) you'll get turned down and rejected.
