I'm generally an honest person.
For one thing, it's easier to just tell the truth and accept the consequences than to try to remember some story. For another reason, there's nothing in my life worth lying about. I don't hold any state secrets. I'm not cheating on my wife. The facts in my life can't bother anyone and if my opinions step on somebody's toes that's just too bad. They're still my opinion.
But when I fall asleep somewhere besides in my bed, I'm a different man. I'm a stinking liar.
I'll be sitting on the couch with the missus, watching some insipid Hallmark movie and start nodding off. She nudges me and say "wake up," and I"m like, "I am awake."
Next thing I know I wake up in the middle of the night all alone in the living room and I wonder, "why the heck did I lie?" What's so embarrassing about falling asleep?
But my sleepy mind will do it every time.
Are you falling asleep? Nope. Not me.
