The time of departure will be delayed by the square of the number
of people involved. Simply stated, if I wish to leave the city at
5 PM, I will most likely depart at 5:01. If I am to meet a friend,
the time of departure becomes 5:04. If we were to meet another couple,
we won't be on out way before 5:16, and so on.
