A little girl goes up to a preacher one day to confess her sins

"I believe I am guilty of the sin of vanity," the girl told the preacher.

To which the preacher responds "Why do you think that."

The girl tells him "Well every morning I look at myself in the mirror and think about how beautiful I am"

Then the preacher tells the girl "Oh don't worry, that's not a sin, that's just a mistake"
