what is the word, in any language, for that set of thoughts to which you drift when time and occasion allow? these are not obsessive or otherwise unwanted thoughts, but rather, metaphorically, more like a comfortable chair and the sitting you do there. for me, this “thing” lately is the introduction i’ll provide to enrolled freshman on the first day of our fall seminar. for a friend, it might be the various rearrangements of furniture she could perform in the living room. for my mother, i suspect it is a set of thoughts about the great dishes she has, and will make. so, regardless of the content, what does one call this “thing”?
