He was very sorry.
The same sort of sorrow.

And his attention being drawn to this unpleasant state, Stevie shuffled his feet.

His feelings were habitually manifested by the agitation of his limbs.
"Keep your feet quiet, dear," said Mrs Verloc, with authority and tenderness; then turning towards her husband in an indifferent voice, the masterly achievement of instinctive tact: "Are you going out to-night ?" she asked.
The mere suggestion seemed repugnant to Mr Verloc.

He shook his head moodily, and then sat still with downcast eyes, looking at the piece of cheese on his plate for a whole minute.

At the end of that time he got up, and went out--went right out in the clatter of the shop-door bell.
He acted thus inconsistently, not from any desire to make himself unpleasant, but because of an unconquerable restlessness.
