30. If you could go back to one time period in your life between the age of 0-18, what year would you choose and why?

I hate questions like this since I wouldn't go back just in case it would change too much. Since I'm forced to , I will go with 0 and hope I'm not so over sensitive.  I doubt my childhood was as bad as I recall because I always get my feelings hurt easily but I know for certain I was lonely alot.
