Here is a little story on how I became a brony.
May 5th 2012, it was free comic book day. My dad took me, my brother and sister to a comic book store. They had given us these bags to put them in. I noticed that the bag had a blue pony on it (which I now know is Rainbow Dash). I didn't want the bag anymore, but I kept it for the time being and threw it out later. In September, I had gotten a 1 month free trial of Netflix. I didn't start watching the show right away because of all the other shows and movies, but October 1st early in the morning, I watched the first four episodes. I couldn't watch anymore episodes because my free trial had ended a few days later, but I was able to find them on YouTube. I didn't start getting into it until I saw The Cutie Mark Chronicles on the second of February in 2013 and that is when I fully became a Brony.
