That reminds of a time when my DD, who was either 5 or 6, decided to participate in a school fundraising run. The run was a mile long, and turned out to be much more than she anticipated. She got a side ache and was way, way, behind. In fact, everyone had kind of moved on by the time she approached the end of the course. We made her walk all the way to the finish line (we walked with her)and then to reinforce our message to her, we rented Cool Runnings that night (one of my FAVORITE movies both for enjoyability and for message--there is some unfortunate language and a big fight scene we could have done without at age 5, but no harm done ;)). Even though I felt kind of mean at the time, I've never regretted having her finish the course. And Cool Runnings continues to be a family fav!
