Isabelle manoeuvred herself and Froggy Parker, freshman at Harvard, with whom she had once played hop-scotch, to a seat on the stairs.

A humorous reference to the past was all she needed.

The things Isabelle could do socially with one idea were remarkable.

First, she repeated it rapturously in an enthusiastic contralto with a soupcon of Southern accent; then she held it off at a distance and smiled at it--her wonderful smile; then she delivered it in variations and played a sort of mental catch with it, all this in the nominal form of dialogue.

Froggy was fascinated and quite unconscious that this was being done, not for him, but for the green eyes that glistened under the shining carefully watered hair, a little to her left, for Isabelle had discovered Amory.
