I thought I'd answer my own question, and tell you exactly what Joshua is doing...
He's very busy at appointments--teaching eager investigators. (He also has some that aren't quite so eager to learn, but hey--that's life.)
He occasionally spies on me. (I think most of the time he approves.)
He's meeting a lot of interesting people. Of course they're all good. Of course some of them are girls. (Now, I know you think I'm crazy to think that there's any chance he could possibly have any type of "feelings" for anybody... uhh hello--he's still a male.)
He likes finding other people who were also hooked up to tons of tubes and ended up dying in a hospital. Ya know, they talk about how annoying it was to have all those tubes in them and especially the one down their throat, constantly gagging them. (But out of respect to their mothers, they don't laugh about it--even if now they think it's funny.)
Joshua always makes good decisions. He's one of those super-valiant-obedient-types. (I know what your'e thinking, but it's not always that simple--he still has to make decisions.)
He's learning a lot about Tonga. (Hmm, I think he even goes to visit every so often.)
He runs into famous people all the time, but doesn't think anything of it. (I mean, he still acts impressed.)
