It's been my experience that as soon as kids go to school, their parents become completely ignorant, and no longer possess any worthwhile knowledge. All wisdom previously considered the domain of their parents is magically transferred to the teacher. Nothing you can say as a parent will budge your child from this viewpoint.
My daughter, Laura, seems most affected by this transition. Her teacher, Mrs M, has achieved the status of some sort of deity, and every word she utters is the gospel truth. Once, when I dared to dispute what Mrs M had said regarding a medical matter, I was howled down by my daughter, as she wailed tearily, "But Mrs M said so". Mrs M is an experienced and excellent teacher, and seems very switched-on, but as a mother and doctor, I felt entitled to correct the minor mistruth. It seems I was out of line. Mrs M rules supreme.
It was with great amusement, and a sense of pride in my questioning son, that I overheard the following conversation:
Laura: "Mrs Marshall says that you should keep trying foods you don't like to eat. She says if you eat something you don't like every day for two weeks, then your tastebuds will adjust, and you'll start to like the food."
Ben looked sceptical. There was a brief pause.
Ben: "So...... what about if you tried to eat poo every day for two weeks?"
(I couldn't wipe the grin off my face)
