Sidebar on the hike, John: at one point Joe and Bri were marching off ahead of Barb and I, and they were getting a bit out of sight. Bri turns to Joe and says, "We need to stop and wait for our parents." Our parents. From that point on, Barb and I referred to Joe as "son", and the two of them as "you kids". Instead of "Uncle Joe", it became Joe-Bro.
Like I said, it's just a lot of fun hiking with Joe!
