If you sometimes punish your children for their bug reports, you will raise at least one child who dreads telling you when something is wrong.

I was once, as a teenager, a passenger in a serious car accident that possibly could have been averted had (justified) fear of my father's anger not caused me to hesitate for a moment to tell him that he was doing an unsafe driving thing and that he was pulling out into oncoming traffic without adequate visibility (he only has one eye.)
