Children's fortune-telling influence _ Does children's fortune-telling influence fortune?

Why does the old man say it is not good for children to do divination?

Maybe it's the age! Do you think if a child is doomed by others when he is a few years old or a teenager, no matter whether superstition is credible or not, how much influence will it have on her (his) later life? When we were young, we didn't understand or believe it. That's because we are young, but adults understand and believe, so we don't want to tell fortune when our children are very young. Fate is not fixed. They want their children to be older than anyone else.
