In some ways a lot has changed inside, but you can't really see that from a picture.  If you look closely you can see the passage of time in a different way.  Take a look at the shirt.  This was the same shirt I was wearing in the picture of me leaving for my trip.  Notice how the shirt is different between the two pictures.  The shirt has faded and the collar has frayed.  I hope the same thing hasn't happened to me.
