Fillmore - I think his nickname should be the mayor.  As we're walking yesterday and this morning, as cars drive by or people walk by, he has to stop and look at them as if he's greeting them and saying hello.  It is hilarious.  Yesterday one of your neighbors pulled into their driveway as we were walking back and he turned it up a notch to walk faster to try to get over to say hello.  Funny dog!  He's doing just great.
