There are two theories (that I know of) concerning saying "Bless you" to a person who sneezed. One is that people used to believe a person sneezes out their good luck, or something like that, so we say, "Bless you" to wish them more good luck. The other is that a person sneezes out evil demons inside them, so the "Bless you" is like a cheer, because you did a good thing.

Prayer is in any kid's life on the days when he gets a pop quiz or a test in school.
