How old must a girl be to get married?

What if, instead of in a country like Mali, a grown man appeared on your doorstep and asked to marry your 13-year-old daughter?

The BØRNEfonden Danmark tries to give us an idea of that situation, by filming the reactions of unsuspecting Danish parents who were not aware that they were participating in a social experiment!

The parents' shocked expressions should be enough to explain why the controversial custom of child brides should not exist. Anywhere.
