I left the hotel at 4:45 AM after just 3 hours of sleep to head for the Berlin Tegel airport. I flew from Berlin to Milan.  There was a short layover, and then I flew directly to Atlanta (10 hour flight).  I thought I might sleep on the plane, but I had an aisle seat.   I recently read that airplane bathrooms are the 2nd most dirty things (behind your kitchen sink), and I have to agree.  I tried my best to wash my hands and keep them clean until I got back into my seat - but it proved difficult.  I went through customs in Atlanta and rechecked my bags to fly into Chattanooga.  I finally got into CHA at 6:30 PM after 17 hours of traveling.  I gained 6 hours, so it felt like 12:30 AM to me.  Bob and Nathan were waiting for me.  It was an overwhelming time.  I was exhausted and saw them for the first time in over 3 weeks.  One of my bags didn't make it, so we had to file a lost baggage report.  We picked up something to eat and headed home.  Nathan wanted me to sit in the back seat with him.   Getting home, it seemed that Belle (our basset hound) didn't think I was ever coming back.  She got excited and tried to jump, but she can't jump much anymore.  Coming in the house, everything seemed so big.  Big TVs, big rooms.  It's funny how you get accustomed to certain things over such a short period of time.  I slept for about 9 hours, but I am still tired somehow.  I got on the scales fearing how much weight I had gained.  I was pleasantly surprised to see that I had lost about 3 pounds.  I guess all the walking did some good.  I'll post some more comments as I reflect on the trip and get my brain around the whole adventure.
