"Did it get a bit late last night? Can't keep your eyes open?"
Again, the student agreed. Rolf flashed a huge smile and in a singsong voice said "then I have something for you!". He walked over to his bag, pulled out a stuffed animal and a tiny embroidered pillow. (I have a grainy photo of them somewhere).
Rolf tiptoed up to the student, put the pillow in front of him, and as the student rested his head on the pillow Rolf gave him a pat on the head.
After this Rolf went back, said that if you're that tired it's better to sleep in your own bed. He resumed the lecture, picking up in the middle of the sentence where he'd stopped. No one slept in his class for the rest of the course.
He always wore the same striped sweater. At one point, he took a break to drink some water and remove his sweater. But beneath the sweater was another identical sweater!
I assume everything he did was very well-planned and part of his pedagogic system and routine, but it was often hard to tell if he was acting, or if he was actually being serious but eccentric.
