In the beginning... I had a very different picture of Bronies in mind! I wasn't a hater, but I thought that Bronies were these tough dudes who go to the gym 10 times a week. I don't even know how I got that image into my mind xD
Anyway in school we had an art project and a good friend of mine said "Hey, why don't you draw Rainbow Dash!" and was like "What?". He isn't even a Brony, but he likes Rainbow Dash...
So I drew Rainbow Dash. That was the "first contact" with ponies.
Then about a month after that I met a girl, who was rambling on twitter how she really liked My little pony and could not stop watching it.
I asked her "is it good?", she responded "if you like unicorns, pegasi and sparkles."
At that point I was thinking to myself "Yeah, sounds like you would like it." xD
I watched the first two episodes and loved them. I think when I first heard "Winter Wrap Up", I fully considered myself a Brony and got 20% cooler.
