After dinner, I read them the stories and parables from the colourful children's bible.

"Jesus said, 'You should build a house on a rock, like this, but not on the sand. Because when the storm comes, the house on the rock will stay strong and the house on the sand will be blown away."

EggEgg added another piece of wisdom, "And you should build a house with bricks too."

"Bricks?" I was puzzled.

EggEgg nodded. "Yes, just like the story of the three little pigs. The house with bricks will not be blown away."
