I’m too tired to talk about it.  I’m due to find my boarding gate for the London to Johannesburg, South Africa leg of our flight…about 10 hours long.  We leave at 7:00 pm…in a few minutes.  We left Buenos Aires yesterday afternoon (just after lunch) and arrived here in London this morning at 7:00.  London was a blast.  We toured from the top of a double decker bus.  We cruised on the Thames River.  We ate fish and chips in a Pub.  We saw a lot and it was beautiful.  I would love to come back here again.  But right now…I’m too tired to talk about it.
