Ciao.

Once again, at the grocery store.
The guy in front of me paid his bill, grabbed his bag, turned and yelled, "Bye!" as he walked out.

The checkout girl waved and then halfway through saying "Goodbye" realized he wasn't talking to her but to his friend behind me. She sort of grinned and said, "Oh, sorry."

The guy behind me said, "What are you talking about? That was a general goodbye to all of us. Of course you should wave. I mean I'm a little disappointed that she (pointing at me) didn't say goodbye too. Rude."

I love my neighborhood because people actually talk to strangers.
