Nobody should lie - to a child, at least - it is unforgivable. Children have been exploited for centuries just because they are willing to trust. You can lie to them very easily and they will trust you. If you are a father, a mother, they will think you are bound to be true. That's how the whole of humanity lives in corruption, in a very slippery mud of lies told to children for centuries. If we can do just one thing, a simple thing - not lie to children and to confess to them our ignorance - then we will be religious and we will put them on the path of religion. Children are innocent: leave them not your so-called knowledge. But you yourself must first be innocent, unlying, true.
