"But, youth can be, well... stupid."
Adults are much better at hiding intentions and denying the inherent risk about to be undertaken. It is a skill we all have to learn to avoid the wrath of 'the boss', 'the wife', or the 'forum member'.
Honesty is always the best policy, but is often couched in the terms of "considering", "I wonder what would happen if...", and "Maybe". Without those qualifiers other 'adults' tend to become overly concerned, especially if you are venturing outside 'their' sphere of comfort. It's always well intentioned, but sometimes 'overprotective'.
Those of us not used to dealing with 'youth' are to polite to say "What! are you Kidding?!!" Give us time Evan, we'll catch on.
