Bahahahahahaha! 2-3 paragraphs? Man, people are lucky if they get me to fill out a bg in complete sentences these days! I answer the questions and that's that. I still don't get why half the questions asked about mortals in a bg are in there. Is it REALLY relevant to the game if my character was a precocious child that couldn't sit still and enjoyed wearing rainboots with blue tutus? Does it matter whether they got through school by studying and doing extra credit or because they're naturally gifted? No, not really. So long as what the character does and how they act fits the stats they have, it doesn't really matter HOW they got there.
Bonus silly points for those questions being asked of Vampires or Changelings. Characters that have potentially lived long/been through enough for that childhood to be completely irrelevant to anything.
