On my way to work every morning, I drive past Davies Medical Center. Today, I stopped midblock to create a little traffic opening so an ambulance could get out of the parking lot.
When I checked my email later there was a message from a friend whom I'd not seen in several months.
Subject heading: Hi!
Message: Hey, thanks for letting that ambulance out of Davies! That was me :-)
There's a moral here somewhere. Particularly (though I hope not solely) if you're personally acquainted with any paramedics.
