I never knew that Heathrow was so huge!

 
Here we are, coming into Heathrow airport at dawn.  A long flight, but we got lucky; not a full flight, and the woman next to me changed to an empty row once we got going.  Still, we are two very tired puppies.  We had done some research ahead of time, and thought that we were going to be leaving from the same terminal in which we arrived; much to our chagrin we found that they don't post your gate details until about 40 minutes before the flight, and as it turned out, we came into terminal 3 and had to leave from terminal 5, which involves taking a bus!  I think terminal 5 must be 20 miles away. So we get to terminal 5 and have to go through security again, and Randy's briefcase causes a holdup; all over a travel sized bottle of mouthwash, but at least we were in much better shape than the woman who was about to lose it as she had somehow lost her paper with her proof of negative covid test on it.  Everone was super polite and pleasant; you just can't beat that English accent for putting you in a good mood.  On to Athens!
