Usage: Thoughtful, Considerate. He who is habitually
thoughtful rarely neglects his duty or his true
interest; he who is considerate pauses to reflect and
guard himself against error. One who is not thoughtful
by nature, if he can be made considerate, will usually
be guarded against serious mistakes. "He who is
thoughtful does not forget his duty; he who is
considerate pauses, and considers properly what is his
duty. It is a recommendation to a subordinate person
to be thoughtful in doing what is wished of him; it is
the recommendation of a confidential person to be
considerate, as he has often to judge according to his
own discretion." --Crabb.
