Aegrotat

Ephraim: What happened?
Rahmat: His head collided with a roadsign, how do you DO that on an Indian moped which won't even go up a hill with engine on full bore??? I ask you. Anyway, surgery will probably sort out the physical injuries.
Ephraim: But what caused it? An ordinary functioning human doesn’t just ride around head-butting signposts.
Rahmat: He got nervy about his exams, took a few too many tranqs and forgot.
Ephraim: Forgot.
Rahmat: Forgot what he was taking, about the meaning of life, and after he woke up in ER, he’d forgotten who was.
Ephraim: Tut tut. Exams.
Rahmat: Going for an aegrotat.
