How do you flirt with a guy if your 13?

To flirt with a guy when you're 13, my age, you just talk to him, laugh with him, make jokes, when you get into a conversation with a few people with him there, then just be yourself and make jokes. No guy is worth having if you pretend to be somebody you're not and then he loves you for who you're not! If he likes you back when you be yourself, then he likes you for real!
