Your not fooling anyone other than other Catholics. One only needs to go to Catholic prayer sites to see that Catholics indeed do pray TO Mary asking her to do things. The words of those prayers assume she has the same powers as God has. Catholics need to stop using that "we don't pray to her" line. By the Catholic Churches own admission they do indeed pray TO Mary.
Even in this “story”, the credit and praise for the healing was given TO Mary and not Almighty God.
