Who's Knocking?

I have had some strange things happen to me but this is high on my list of "you have got to be kidding me". Three days ago I was in my living room when I heard an unusual knock at my front door. It was pretty light and very rapid and it sent my little Yorkie into his usual fits of barking when someone comes over. I wasn't expecting anyone so my oldest son went to the door and peered through the glass. He saw no one but again we heard the knocking. He threw the door open and saw this crazy little squirrel run from our porch out across the yard. Jacob was convinced that the squirrel was knocking on our door but I just thought he was messing with my head since that is one of his favorite pastimes. So then yesterday afternoon I heard the same odd knocking at my door and this time I went to answer it. Sure enough, as I opened the front door, a squirrel with his hands full drops his acorns and takes off across my front yard. Now, I have to say, the Mormons and the Jehovah's Witnesses have come calling and left me some pretty strange literature, but never has a squirrel beat on my door with an acorn and then run.
So why and I writing about this? Can't say for sure. Victor Borge once said that "laughter is the shortest distance between two people", so perhaps you and I are alot closer if we can both laugh at the nuts that have shown up at my front door!
