if, after a morning hoiking books hither and yon at the charity shop, if i am falling asleep at lunch, what conclusion should be drawn? a) i am lazy and a layabout b) i am hungry to the point that the system is trying to shut down (like my laptop battery) c) i am old d) i am so ——ing tired i can’t even. tbh my upbringing gave me a) as the first answer, but i am beginning to question the truth of that.
