This is a great song (and I love Ed Trickett's singing of it -- first place I'd heard it). I know kids today for whom this song seems to be written -- and adults who were once those kids and who never learned to communicate any other way than standing on someone's toe because at least "ouch" is a response...
When I run into one of them, I often find myself humming or singing this song, and reminding myself that people surely do have different ways of expressing their needs.
