Just to annoy my dear friend Amauro, I will tell the story of how he got the title trowing-knives-guy ^^
Amauro and I came from a different elementary school than our new friends so they didn't know us at all on the first day of 6th grade. Kyan was the one I really befriended first, she introduced me to everyone else (Kaly, Lina, Luna, Crystal, and our non-otaku friend Sara). So later on in the school year I had Kyan over, and while we were outside she saw Amauro(who lives next door to me) playing catch with his little brother. Kyan, being hyped up on sugar, thought he was throwing knives at a tree and yelled "Hey! Mister throwing-knives-guy!!"....it went on from there. Eventually I just invited Amauro over so Kyan would calm down and realize it was a ball, not knives. But she insisted on calling him throwing-knives-guy, so the name stuck ^^
He really does hate that story because his brother decided to throw the ball when Amauro was distracted and it hit his shoulder pretty hard....Kyan had a good laugh about that....
