Nothing to do with hygiene.

While walking through the Le Marais I came across this decorative car belonging to a flower shop. For a moment I thought I was in San Francisco as opposed to Paris. Wait. Come to think of it there are plants associated with cleanliness. The Spider Plant is reported to purify air. Perhaps I should start traveling with one on an airplane. I will have to wade through the customs guidelines of different countries. Soil could be an issue. Perhaps I could turn the plant into a hat to avoid that issue. There is nothing strange about that.
