The floss on the Dart

Sir, – On the Dart recently, a young man opposite, thankfully not, beside me, spent a good 10 minutes carefully flossing his teeth. I was surprised he didn’t then produce the requisite (these days) bottle of water and indeed tooth brush.

The words “thankful” and “small mercies” spring to mind. – Yours, etc,
