The saying may be worn but it is very true.
Alas! the saying is still in force and true today.
My grand son had to be taken out of a Public school in Westchester co. New York and enrolled in a private school.
The teachers were not teaching and the Principle and Superintendent refused to do anything. Sadly these two women were more interested in their personal relationship.
The move costs my Daughter $10,000 per year, beyond the $7000 she pays in real estate taxes, in tuition and hugh additional costs in travel.
In the grade school in Harwich Mass. the teachers are involved in teaching the mechanics of Homosexual sex.
There may be good teachers, and I know some, but they are overshadowed by the mindless frauds controlled by the Unions.
