I haven't really told my father, but think he would bother anyways, and my friends know I'm a brony, and they where a little "Hmm...." in the beginning, but now there cool about it... at least most of the time, they make fun of it sometimes, but i just laugh with them
I'm not hiding my Bronyness form anyone, if i like to post something about Ponies on facebook, i do so, and if i wan't a Ponie pic i my skype, i do so
