From The Trick Is To Keep Breathing

Other people. Other people interest me. How they manage. There are several possibilities.

1. They are just as confused as me but they aren't letting on.
2. They don't know they don't know what the point is.
3. They don't understand they don't know what the point is.
4. They don't mind they don't know what the point is.
5. They don't even know there are any questions.

The first is too paranoid. Paranoia is a joke. I will not be a joke, Rejected on the grounds of unpalatability. The second unlikely: it rests of the unpleasant assumption that other people can't work out what I can work out. Since modesty is a becoming trait in a woman, I reject the second. The third is interesting and enviable but gets things no further forward. One can hardly unknow something, ie I am in no position to alter the facts. The fifth makes me lonely and is rejected on the same modesty clause as postulation 2 (see above.)

That leaves me with the fourth.
