Out of the mouths of babes

[Dunno]

Attending a wedding for the first time, a little girl whispered
to her mother, "Why is the bride dressed in white?"

"Because white is the color of happiness and today is the
happiest day of her life." Her mother tried to explain, keeping
it simple.

The child thought about this for a moment, then said, "So, why
is the groom wearing black?"
