When you are 38 1/2 weeks pregnant, it is not a good idea to call a friend three times in one hour and leave two messages.  It doesn’t matter if you know that you’re not in labor or distress.  It doesn’t matter if you think, “hmmm, maybe she’s putting her kids to bed” or “maybe she turned her ringer off”.  It doesn’t matter that you’re actually calling to answer a question that she has asked you.  Just don’t do it.  You might give your friend a heart attack!  🙂
