...Could you take a bit of your power, grow it in a lab and then pass it out to people? *shot*
Wait, on the other hand, I do seem to have a tendency to be rather invisible to people outside my family. Once a girl came into our classroom asking where I was and thought I wasn't there. And i was sitting less than 6 feet away. That happened again with a teacher who was sitting closer than that and thought I was absent.
