Actually they learn to get all the facts first. They are not so dumb to realize that they are getting a valuable lesson.
In fact my 21 year old who has left the house thanks me for those lessons now that he is in the real world.
Yet, how can I ensure that Pops is going to give me all of the facts when I ask for them?
If there are "conditions" there could be an unstated condition such as the condition that all facts will not be submitted, even when asked for.
