I have discovered a few things about "business" calls (and I use that term loosely).

Second, the more important the call is, the more phone tag you will play with the person you are trying to contact. Third, if you are so determined not to miss an important return call that you leave both your home and mobile numbers, two people will miraculously return calls at the same time, one on each phone. Fourth, they are not amused when you ask them to please hold, and have one of your kids hum "Feelings" for ten minutes. Fifth, the minute you are asked to leave a message and hear the beep, your brain shuts down and you forget how to say anything but "um". Sixth, the minute you actually get an important call, the doorbell will ring, someone will get hurt or get in an argument with a sibling, or something will start on fire.
