Today the North Tama Class of 2012 graduates. They were kindergartners when I was a senior, so they were the last students I shared the school with. The Class of 2019, just finishing fifth grade, was born after I graduated.
Where did I put my Metamucil?
P.S. There is nothing that makes you feel older faster than seeing a new addition to the school.
P.P.S. Possible exception: Seeing your school building closed. Lots of Iowa students get that instead.
