Actually, that has nothing to do with anything, except for the fact that yesterday at a salad bar the beets got my sister and I discussing the old Nickelodeon cartoon, "Doug".  If you have no idea what I am talking about, here is what we were referencing: www.youtube.com/watch?v=p7c3bQQmwVE.
E's flight home got diverted due to low visibility last night, causing him to not arrive home until sometime after 2:30 in the morning.  I heard the door; so did the dog.  I am pleased to report that the dog went nuts!  I have never heard such a vicious bark come from that sweet little thing!  As soon as I reassured her and called out to E to speak so she could hear his voice, she dissolved into tail-wagging excitement in her kennel.  She just seemed to never know a stranger, which made me think she wouldn't make much of a watchdog.  But she knew something wasn't right about the door being opened in the middle of the night.  She may be quite the protector after all.
