As a teacher he was always kind and patient (despite our
undoubtedly painful mutilations of his beloved Russian language),
but we knew he could have a scathing tongue from his occasional
digressions on the USSR, Sigmund Freud, and other objects of his
scorn. He was fascinating both to watch and to listen to. In
1942-43 he was slim and elegant. Although smoking was not
permitted in the classrooms at Wellesley, he always had a lighted
cigarette in his hand, and since there were no ashtrays we used
to watch in rapt anticipation as the ash grew until it dropped to
the floor.

Ложная память, или я всё же видал фотографию Набокова с трубкой?
