Where Did I Come From?

For CJ's birthday we got her this cute book on Where You Came From. Obviously it didn't answer the question because tonight on the way home from the pool she asked if we found her on the computer. Nope. We didn't buy you on Craigslist sweetie. Then as Mama sat in here on the computer she could hear CJ and Daddy going to bed and CJ asked about "body builders" and if a body builder made her. Guess she must have heard Mama talking about a local woman who used to be a body builder over dinner and although that does seem like a logical explanation, it isn't quite right either...
