Good for you, John. Sounds like you are on the right track! People that try to give you grief are at all levels of teaching and they just dig themselves into a hole. I had one who was a problem for everyone in many different departments and the day she left (or was "encouraged" to) was widely celebrated. Teaching has so many rewards - just seeing the light in a child's eyes - even at university level, when they've understood something or succeeded in a task is awesome! Celebrate and recognize all the beautiful moments that come your way! Do the happy dance with your kids!
