You assume quite alot.
Almost all of life's experiences have positive AND negative aspects. Learning one of life's greatest lessons from an older, considerate, and experienced teacher (pardon the pun) is a blessing more than a curse. The French are not complete idiots.
You are perfectly welcome to teach your boys that life is black and white, and to believe so yourself. But in my opinion you are completely wrong. In my experience there are only shades of gray.
This thread has been the most humorous and human I have yet seen on FR. But your posts are to me, beyond the bounds of humanity. Good luck with your sons. Try not to be too disappointed when they prove themselves to be human.
