If I may be so immodest, of course I'm right. I was social studies teacher of the year at my high school in 2001. Teaching is one of the very few things I do very well. But you did the right thing. Something I drill into my students daily. Don't take anything anybody says as being absolutely true. Check it yourself. Find the other side. Especially: Look for a person's AGENDA when you are told something!
My classes always seem to fill first. I have had parents with children who had me in the past call the school to demand the younger sibling be put in my classes or moved from another class into mine. That's a responsibility I take seriously and so I do my homework before I open my mouth. Seventeen years and counting.
A gifted teacher creates a perfect and wholesome hunger in any student. Thank you for teaching; and teaching so well.
