Wrapping things up with a message

I felt that the main message in Great Expectations was to not have regrets.  Charles Dicken constantly shows that as you live your life you don't want to do anything that you will regret later on.  This is a universal experiance for everyone. Everyone knows what it's like to have done something and regretted it afterwords.  You realize what hass happened and, if you're a true person, only wish to right the wrong.
