Dog Tired

Have you ever noticed how a dog can run and jump and play ... then seemingly in the next instant be fast asleep.  When a person feels like they could collapse and be instantly asleep they are Dog Tired.

 

And if someone feels like they could sleep for a week ... where they would continue to sleep no matter what was going on around them, they might be at an even more extreme level ... Dead Dog Tired.  Which is how I find myself right now, so until tomorrow...
