There is this look about a reader. A look another reader knows intimately. The look that shows politeness, but a really fervent wish, to get the hello over so they can return to their really good book.
True book readers know…it feels quite lovely to sit on the bus with someone you’ve known, in passing, from riding the bus together the last 5 years, and be quite happy not to talk to them..and they to you. All because you both respect the seeker of knowledge code. Say hello, be kind, let them know you don’t mind by opening your own book. Repeat daily.
