how not to clean the porch

Before my parents and sister came a few weeks ago, I began the arduous job of cleaning a very nasty back porch. Between spiders and rain residue, it was a mess. I was pleased with the progress I was making:

 Before

 And after.

 

And then the crazy happened. I was outsmarted by my dog. He had been coming up, going side to side, then leaving. Then he came up and just sat down after I petted him. So I kept working, not thinking anything about it, until I reached for the paper towels and they were gone.

 

My own dog paper-towelled my yard.

And that was the end of cleaning off the porch.
