How is your toilet feeling?

Many years ago I worked with a young boy who had autism. He always wanted to know if the toilet was happy or sad. He had been taught that people's mouths turned up when they were happy and down when they were sad, and just assumed that toilets expressed themselves in the same way.

I must admit that, 20 years later, I still notice a toilet's expression. And now, so will you.

This toilet is happy. Some toilets are sad. Others are just rather bemused.
