"What is your worst trait?" and "What is your best trait?" were the two questions that jumpstarted these two characters. My designs had to reflect the characteristics I picked perfectly to be successes. I had to pick two words that I felt were both accurate, but interesting enough to spend a week wrestling over. Most people went with 'shy' on the first, but the second one got the funniest responses, things like 'fertile' and 'sensual.'
