Just back from Shirley's house. It's the farewell dinner for me. She gave me a pain killer cream for my gift. How sad. I'm leaving...

Earlier in the afternoon she brought this huge carpet cleaner to help me clean the carpet. It's a very interesting machine. It has brushes at the bottom. To use it, it's more or less like a vacuum cleaner. Just push back and forth.

The first time, hold a button so the detergent goes down into the carpet. The second time, release the detergent button so clean water goes down to raise the carpet. And now, the carpet smells of the detergent!

I cannot imagine the carpet is so dirty though I vacuum clean all the time. Yet I haven't got sick from the dirt. How amazing.
