I don't like to talk about my past that much. But here it is:

My mother and father were never home. At first I didn't realize that it was because they didn't want me in trouble due to their work, and I was lonely. But my parents would bring me a present every time they came home. Once it was an Indian style clothing set with matching shoes, and another time it was a glass sculpture of a dolphin. But as I got older, the more exotic and dangerous the gifts became. One time, I got a well crafted set of daggers that came with sheaths, and some lessons on how to use them. Another time, I got some clothes that I never out grew, no matter how much I did grow (Strange I know, but hey! There are much crazier things that happen in the future). If I had looked, I would have seen that all wasn't right sooner rather than later, but I didn't want to see it. After all I didn't want to know why mom had a bloody bandage when she came home from a particularly long work session. But hey! You wouldn't want to know either. But one night, after they had left for the next work session, someone broke into the house. I didn't know what to do, but he threatened me. I didn't mind that, the kids at my school scared me more than some unnamed burglar because I wasn't aloud to hurt them, no matter what they did to me. I had started keeping my daggers on my person at all times and my lessons had helped me to know what to do. My parents had, without me realizing it, had an alarm system that alerted them when ever I was in danger. But by the time they had gotten back, the burglar had tried to kill me and was thus already dead, by one of my daggers. That was the thing that started my intensive training to become an assassin. I wanted to be with my family, and both mother and father were assassins, so I decided to become one as well and then I could join them on their missions. Childish, I know, but I was eight. What do you expect? But when I told them this, mother wasn't very please and father was like 'this was going to happen eventually'.
I was still going to become an assassin though and they didn't argue with me, which was good because looking back now I don't know if I would have won.
Three years later I was ready to start participating in a family tradition that dated back centuries. I was given a cloak that was a very special cloak, no matter what was under it it looked like there was only my body, and it had a heating and cooling system in it. And then I was told that I would be able to turn into animals, but first I had to get used to half forms of the animal before I did the full transformation.
And now up to present, I have mastered many forms and I can now work alone, but I still prefer to do assassinations with mother and father.
