Phone nonsense

I've gotten calls from the Tucson Symphony the past two nights, but they don't leave a message. Caller ID says they called, but why would you not at least say something to the machine? They probably just want me to join so I can get into their exclusive club room or something. :-)

What sucks is they don't have any performances scheduled until autumn, since they figure nobody wants to leave their homes in the summer time. Reasonable assumption, I suppose...
