possible.

But he became aware of something unusual and discomforting in the
atmosphere, and when his grandmother said sternly, "Sit down!" and he
turned on her to offer his own opinion on the matter, he found the keen
dark eyes gazing out at him from under the shadowy penthouse of the
great black sun-bonnet, with so intent and compelling a stare that his
mouth closed without saying a word. He climbed up on to a chair and
twisted his feet round the legs by way of anchorage.

Then he sat up and stared back at Grannie, and as an exhibition of
nonchalance and high spirit, put out his tongue at her.

Grannie only looked at him.

And, bit by bit, the tongue withdrew, and only the gaping mouth was
left, and above it a pair of frightened green eyes, transmitting to the
perverse little soul within new impressions and vague terrors.

Before long his left arm went up over his face to shut out the sight of
Grannie's dreadful staring eyes, and when, after a sufficient interval,
he ventured a peep at her and found her eyes still fixed on him, he
howled, "Take it off! Take it off!" and slipped his anchors and slid to
the floor, hunching his back at this tormentor who could beat him on his
own ground.

For that week he gave no trouble to any one. But after it he never went
near Grannie's room, and for years he never spoke to her. When he passed
her open door, or in front of her window, he hunched his shoulder
protectively and averted his eyes.
