Circumspect: (adj) wary and unwilling to take risks.
I have decided that the best way to protect our country from terrorists is to let moms and dads examine the bags at airports.
Think about it.
If we put these moms and dads in charge at the airport, it would only take about two weeks before frequent flyers would grow weary of bringing along anything
that might be questionable. For after all, not only would it be rejected, but also you would have to listen to the lecture on why it was stupid to consider bringing it in the first place.
Mommys and Daddys are circumspect–careful to a fault.
In the process they possibly spare their children some potential danger, but also plant seeds of suspicion and “Mommy-and-Daddyism” inside them, until such an hour that these children are in charge of their own little offspring, who likewise need to be ferociously protected.
