What really flatters a girl?

Just say sth Nice to her,,Do not come off as needy--treat her like any normal human being but recognize that she's a girl. Be truthful--say what you see... Joke--Girls like Jokes, gimmicks and sarcasms.Drop one to make her smile and then go serous then repeat the circle again... If you say boring things to her your flattering might not do any work as she wants energy and romance not talks on "Dr. Gock's" publications. Be yourself..
