Hello again everyone!  I think I have finally figured out which Pap is which of the two humans I take up residence with.  The dark one is clearly Matthew as you can see from the plane ticket.  I know this since I am sitting on his lap and the ticket is right behind me and I am sitting on his passport which has his picture on it.  They clearly have to match otherwise we would never have gotten through security at this airport.  Let me tell you security is pretty tight.  I even had to go through an x-ray machine.  It was not as bad as I thought but some strange person picked me up and squeezed me a few times.  I almost vomited up my lunch.  Ugh!  Incidentally I'm on my way to London, England.  I've never been there before but I've heard that Jack Russell Terriers originate from Great Britain.  Maybe I'll have an opportunity to do some genealogy research while I'm there.
