Wow, weird! I was right-handed until I was about five, and after that somehow, for whatever reason, I started to write with my left hand, and now I'm fully left-handed! l3
When I was little and learning how to write, I was supposed to be left handed but my mom made me write with my right hand! I was kind of disappointed when she told me that.
Random fact: I kind of don't like being left-handed at times because the ink always smudges. :[
