That's what my expectations where when I first 'joined' the fandom, lol. I really didn't understand why people would make so many OCs about them being orphans and there past haunting them.
-------------------------------
But honestly, before I knew people from MLP Fandom, I would associate them with the "stereo-typical brony". I didn't care what-so-ever about those in the fandom because, hey, that had nothing to do with me. But now that I've actually joined the fandom and have met other bronies on these forums and previous forums, the stereotype that I automatically linked them with never really existed. It was pretty stupid of me to think this way..
Anyways, I guess if you've never interacted with the fandom or you rarely have, you really don't know what to expect. (imo.)
