" It is interesting to note that two people with these opposing philosophies often get married. One has a tendency to be just a little too lenient. The other has a tendency to be just a little too strict. Then the lenient parent thinks he or she needs to be just a little more lenient to make up for the mean old strict parent. The strict parent thinks he or she needs to be just a little more strict to make up for the wishy-washy lenient parent—so they get further and further apart and fight about who is right and who is wrong. In truth they are both being ineffective. "
