most kids nowadays will be able to teach the adults a few things like in my SE class my teacher thought we knew more then him about the subject
reminds me of a DT lesson two years ago. It went something like this.
"Sir? Isn't that saw a bit close to your thumb?"
"Don't worry, I'm fine. I'm just...ARRGGGHHH!!!!"
There was an ambulance at school 15 mintues later. I bet the kid who was thalking to the teacher at the time feels a bit bad now.
