I was at the doctor's waiting room today and bumped into the people who lived next door in my old house. I recognised them and said hello - they were in conversation and so, after a quick "hi" returned to that. That's fair enough. However, when the lady of the couple went off to be seen, I had rather expected to exchange at least pleasantries with her husband. He picked up his book and stuck his head in that, without a glance my way. Maybe I'm being touchy, but I found that rather offensive. I can't say that his company is worth getting particularly excited over... so no real loss. However, I thought it basically ignorant and unfriendly. I got a goodbye as they left, though I think I initiated that.
