Will loves runners. (It must be because it is such a foreign concept...neither of his parents runs.) Anyway, while we're driving, he likes to point out any "nun-ners" that he sees. I always encourage him and say things like "yes, those are runners." But, we've almost exclusively reserved this term for people who are exercising, people we see out running on the sidewalks or in the streets.
So, I was a bit surprised when Will saw two children at his school running from their car to the door and immediately declared them "nun-ners." I am constantly amazed at the way his brain works and the connections that he is making!
