Why?

OK so like every three year old that ever lived, Lindsay askes why about 45 million times a day. Today while I was cleaning a major blowout of Leslie's diaper Lindsay asked about 5 million of her 45 million including "why leslie have a dirty diaper?" and "why is that a bad diaper?" all of her questions, she could have answered herself. Then after I had placed the offensive diaper next to me on the floor, I told Lindsay not to walk on it, she asked why, and I just looked at her. She smiled and said, "why I always ask why mommy?" I told her I thought that was a very good question.
