It hasn't really changed at all - guess it must be ME!
(I wrote a poem like that back when I was a senior in high school for our annual - I can still remember some of it...)
Give me just one hour
to think about once more
All the crazy, lazy, happy days
and what each had in store...
I don't remember it all, but at the end it went on to say that, after looking back again, it really hadn't changed that much - "I guess it must be me!"
