Come on, kid -- would I lie to you? Again?

Once, while waiting in line for the Pirates of the Caribbean ride at Disneyland, I heard parents reassure their young (and obviously apprehensive) son that there was nothing scary or dark inside. I tapped the mother on the shoulder and told her, in a low voice so the boy wouldn't hear, that there were actual several dark places in the attraction as well as some spooky lighting and skeletons. She said that she knew, and that she and her husband had been on the ride lots of times -- which just makes me wonder how they expected their child to ever trust their reassurances again.
