I became a brony about 2 months ago.
For the past year I have watched sfms for entertainment. I stumbled across a video called 1 day off and thought this wasn't so bad. So I clicked on the creators channel who was Herostrain and thought to myself "What is this weird pony crap." I decided to watch immeasurable evil and instantly got hooked on it. I then watched out of the frying pan which I thought was just absolutely amazing.
So I decided to look up pony sfm on youtube and watched a video called my Little Dashie.
After this I read the fanfiction and before I knew it I was getting all emotional about some magic ponies that don't even exist. I didn't think I would actually watch the show but I gave it a try and ended up being addicted to it and joined some PF2 servers and ended up here.
