To undertake an expedition is to extend oneself into a new area. My expedition implied my extension - the very movement of extension. I miss the people I corresponded with. Now I'm not addressing anyone in particular but anyone at all. Now, when that line is broken, suddenly I get all kinds of whims: to reshape the text, draw figures, enlarge and diminish it, though I know that it wouldn't make the few things I want to add more comprehensible.
