The column labeled other can contain the lives that challenge the whole table.

Categories are built out of the cases somebody expected. Whatever did not fit gets swept into a leftover box, and that box is treated as small and uninteresting when it is often where the assumptions behind the whole scheme become visible. The people in it are not exceptions to the pattern so much as evidence that the pattern was drawn too narrowly. What a system calls other is a record of its own limits.

If you keep any kind of list or form, open the leftover category and read what is actually in it. One of those entries usually deserves a name of its own.
