OK so there is this girl at school that I really like :) n I been wantting 2 approach for a while now but I just don't no what 2 say:( can any one give advice on what to say and nothing dirty please

Just walk up to her and say hello and introduce yourself. Ask her what classes she's taking and if she likes them. From there just carry on a normal conversation like you would with a friend.

How old are you and what are your personal interests? Do you know yet any interests of hers?

We are both 16 and yea I no what her interest are

Then invite her to do something with you from her known area(s) of interest. Nothing awkward, just an event and a simple yes/no to do it with you.

Take a deep breath, and say hello, and get to know her.
