I love all of your answers to my question! I think everyone has the right idea! It certainly has made me think. If they had offered Kindergarten when I was a child, I would have started at age 4. The cut off date was November 1st. How sad to stop childhood so soon.
Anyway, I just wanted to say thank you to all who responded to my question. Maybe this will be the topic of my thesis for my masters program. It is all certainly interesting!
