It's amazing how utterly exhausted you can get and not know it. LOL
With traveling, snorkeling, cave tubing, hiking, climbing ruins, trips on a boat, etc without air conditioning in a very humid environment, many of us hit that air conditioning yesterday on that airplane where we were forced into inactivity and we just wilted.
By the time we got off of the plane in Dallas and raced to get on the plane to KC, and got settled, many of my classmates were out cold. LOL I had to wake up 6 of them that were sitting near me, so they could put their seats up and such for landing.
As for me, I slept from about 4 am to around 8:45 when my daughter woke up. I let hubby sleep a few hours longer while I ran errands, got the mail, etc. Then about 1 pm I headed for a nap. After I got up, I ran to the grocery store, and now I am cooking dinner. But I could still use another nap.
I am flat out beat. Yet when I was running around, doing all of the strenous activities, I hardly felt it. LOL
