Thomas Wolfe* and Heraclitus** both had good, if vastly over referenced, points.
To the first I'd agree, except that childhood was not a place I'd ever particularly want to revisit, except in my writing. One might rephrase, "You can't go home again, if home never was one." This trip, I'm getting along with my mother quite well, except for her incessant need to be in my space, which is a problem with mothers generally, I'm sure. It's a minor problem. Mostly, I just want to punch my step-father in the face. Although my mother these days is quite good-natured, he's been a silent sulking and brooding lump on the couch ever since Christmas Eve morning, over what we just don't know. It seems to stem from a conversation we had about eating well, something he doesn't do, but nothing was directed at him, you know. So it's a mystery.
To the second, I'd say that though the geography of the river looks the same, it is true that the matter moving through it is ever a'changing. One is tempted to correct the redundancy or maybe I should say, superfluity, in Heraclitus, as one really can never step into the same river even once. Still, we get his point. If I damaged the proboscis of my mother's husband, it would not really be the same nose the second time fist meets prow.
I hate being negative, especially when everyone's supposed to be putting on their best face, but everyone isn't.
I have a rash over my right eye, and I just can't tell why.
