I suspect that Silas has inherited my hypochondria. (See earlier posting below on my own struggles with this chronic condition.)
Like, right now he may have conjunctivitis, or it may just be a little dust or or other irritant in his eye, making it slightly red.
You see at left what has him concerned. The conjunctive... um, stuff... in his eye is reddish. But he insists that it's conjunctivitis, and doesn't even want to hear a differential diagnosis. This is what leads me to believe that he may have hypochondria.
Oh hey, if you notice the strap across his nose, it doesn't have anything to do with his eye problems. It's just something I'm doing to him.
