feeling nostalgic for something I've never done

If I was in a movie, instead of real life, this is when that song would come on
I would stand up and start walking
all the students would stop and stare
I would pull off my blazer and let down my hair
children would appear and frolic around me
and I would dive into the Chattahoochee
with a bunch of kids
and we'd all splash each other
sometimes I wish I was in a movie
