I like a girl. When she returned to my space, she called me a wet behind the ears, and once asked me to ask her sister to send me candy. What does she mean?
What she means is that she just regards you as her little brother, and she enjoys your obedience to her. But if you really like her, you should take more direct and mature actions, because she feels that you can't give her the care and love of men and women of the same age. So you have to be bold and straightforward.
