passport travels

apparently my passport is having an adventure all on its own, if the tracking number of Fed Ex is to be believe. On its way back to me but it left Alexandria, Virginia, went to Mississauga, Ontario (that bit is good because that's where the airport is in Toronto) but then it arrived in Memphis, Tennessee before it got to the airport in Toronto and has now left Memphis. needless to say, I am totally freaked and have been up for hours hoping for a knock on the door
