['My boss called me the other day to tell me I would be receiving a package the next day.  No other info, but she told me not to open it until I called her.']
So have you gotten to open it yet??
My boss called to tell me that I would be receiving a package the next day, and that I should call her before opening it.  I was really hoping that it was a special award that my company gives to deserving employees, but it turned out to be some personnel paperwork that she needed to go over with me.
