What is your wallpaper on your cell phone of?

i do change my wallpaper every now and then like every month to 2 moths. i do love myself but i will never ever put myself as a wallpaper on my phone. not only i find it freaky but i also think why? 99% of the time the person would not even know who is the person on the phone. the only time i would put a picture of my self as my wallpaper is if there is a bunch of friend or something with me.
