Poetry Friday: Fixed Interval

My daughter and I have spent this week with my parents in Florida, since we had some time off of school for Carnival. My husband and son stayed in Haiti and did manly things. Thinking of their relationship reminded me of this bittersweet poem, which I got in my Poem-A-Day email earlier this month.

Fixed Interval
by Devin Johnston

When he turns fifteen, you'll be fifty-four.
When he turns thirty, you'll be sixty-nine.
This plain arithmetic amazes more
than miracle, the constant difference more
than mere recursion of father in son.
If you reach eighty, he'll be forty-one!

Here's the rest of it.

Here's today's Poetry Friday roundup.
