The most dangerous liars can be the kids’ own parents. If you take a boring job to give your family a high standard of living, as so many people do, you risk infecting your kids with the idea that work is boring.
Most people are doomed in childhood by accepting the axiom that work = pain.
All parents tend to be more conservative for their kids than they would for themselves, simply because, as parents, they share risks more than rewards. If your eight year old son decides to climb a tall tree, or your teenage daughter decides to date the local bad boy, you won’t get a share in the excitement, but if your son falls, or your daughter gets pregnant, you’ll have to deal with the consequences.
