I'm on the Internet for majority of my days, so sometime late 2013 I noticed a number of MLP related posts going around everywhere. I knew what a Brony was, but only to what the Internet had assumed they were. Which isn't true, to my actual surprise! Whenever something becomes mass popular, my curiosity usually gets the best of me and I research.
I went on YouTube and searched 'My Little Pony: FiM' and found the Equestria Girls movie first. I didn't think I was going to think much of MLP, so I just watched that rather than Season one. About twenty minutes into the movie, despite how a handful of the fandom thinks EG was god awful- I enjoyed it. I was super absorbed into the bright colors, the music, then Fluttershy. Fluttershy sold me.
Since then, I watched every season to date, collected some plush dolls, watched the popular videos-- I became a Pegasister.
