DS4 was asking about St. Nicholas the other day. I said he was a good man who lived hundreds of years ago who wanted to share his wealth with the needy. He asked if St. Nick was still alive. I said, no, he died a long time ago. "So who puts the stuff in my shoe?" I got away with "the spirit of st. nick still lives." (DS believes in ghosts, so he thought that was a reasonable answer!)
