The rest of the story...

On the second half of our journey I sat by a lady who had buried her 100 year old father the day before.  She told me, "I sometimes faint on airplanes.  The doctor says it's triggered by high altitudes.  I have a wet washcloth and smelling salts in my purse if something happens."    Lucky for me, she slept most of the trip--well, I think she was sleeping.  I checked a few times to make sure she was breathing and I never had to use the washcloth to wake her up.

 Later, after she came back from the bathroom, she whispered, "I'm really not able to go.  That's twice now.  I've got to get home and start drinking some water."  TMI !!!!!!!
