How is retirement?

I keep getting asked, "How is retirement?"
Well I don't know. I am technically retired, however I have always had summers off so it does not feel like retirement in most ways.
I have noticed that when I drive by the exit for the school, I think about what I need to do and if I should see if my room is ready to start preparing for next year. Then I catch myself. I don't have to go get things ready for next year.
How is retirement... ask me in late August.
