While I encourage my friends and readers to endeavor to approach life with an attitude of wonder, I admit there are times when wondering too much is futile.
Some things are best placed in the category of "that which cannot be known."
For example, the fact that momma has a photo folder entitled "Dexter's Bottom."
Likewise, experience has shown that in most cases, the joyful exclamation of "Oh Dexter! What a great photo op!" should be a signal to empty one's head of any attempt at deep, analytical thought.
Observe in this picture how I have effectively purged my brain of all rational queries and assumed the demeanor of mindlessly obedient dog.
Wait for the phrase "OK! Good dog!" as your all clear to once again enter the world of the sentient.
