I suspect I was the favorite of my hot young German teacher in H.S.
She was wandering around the class explaining, I suppose, some arcane detail of German grammar, when she walked up behind my chair and, well, sort of, uh, nudged..the back of my head for half a minute.
Of course I was far too hellishly dorky to stay after class for special tutoring, or field work, or anything like that.
