It seems like that you support people who lie to children. Probably you do lie some (cover up bs) to your own kids whether they ask you for something by wonder. What a shame. No matter what, truth is the best policy. Always.
No excuse. Lies makes a child's life worse. It also could cause a kid to abuse the parents because of that. My former friend was one of them. He still hates his adoptee parents ever since he was 15 when he found out that they weren't the actual parents. Lies result: unforgiven.
