If the answer to the first question is yes:
Did you hide it away from prying eyes?
Would your parents have flipped if they'd read it?
If the answer to the first question is no:
Did you have someone/thing to confide in as a kid? (My dog. I could tell him anything.)
Were you a wild child or fairly well behaved? (I didn't break any laws, but I did often push my parents to the breaking point, I fear.)
