How your own dad becomes a role model (in a good family), or your brother? Or anyone who makes an impression on you? Human development has many stages. As kids, you look for role models and guides, you are more impressionable. Then with age comes the "I'm myself, so I'm gonna go find myself" part. It's all natural. I can kinda guess from your answers where are you at. You even deny the whole fan-thing and emphasize how you don't "fan over" people so noone else in your mind can. Yes, 14-16 yo girls dont look at Bieber as role model obviously as they scream and cry when they meet him. "Fanning" is different with age and genders and other dynamics etc. But nontheless it exists.
