It doesn't matter

I read this tonight on Story People, and it touched me.

I had a dream & I heard music & there were children standing around, but no one was dancing. I asked a little girl, why not? & she said they didn't know how, or maybe they used to but they forgot & so I started to hop up & down & the children asked me, Is that dancing? & I laughed & said, no, that's hopping, but at least it's a start & soon everyone was hopping & laughing & it didn't matter any more that no one was dancing.
