poem analysis

I feel like he just had a hard transition from childhood to adulthood and he doesnt really know how to deal with it.  He obviously wishes he could go back in time to his childhood.  He captures childhood by giving such good details about when he was younger and from age to age.  I do agree with him that life was more fun and easier when we were younger but there's a point in everybodys life when we have to grow up and become "big kids."
