Sometimes we mistake patience for weakness, but the patient person often realizes that it's much more important for another person to discover his or her own gifts and shortcomings--the patient person doesn't feel a need to "fix" other people, and will sometimes let certain things slide until the other person recognizes the problems. Patient parents often let their kids make the same mistake two or three times because they know that a lesson learned oneself is almost always preferable to a lesson given to us by an authority figure like a parent.
