The frustrations of life...

Ever have those moments where you are doing what was asked but the other person simply isn't living up to their end of the bargain? What do you do to pass the time while you wait for that person? This is what I've been pondering today as sometimes while all one can do is pass the time, there should be other ways to make use of that waiting time. Sometimes I do puzzles or ponder various philosophical points like questioning the purpose of our existence for example.
