A frail old man went to live with his son, daughter-in-law, and a four-year old grandson. The old man's hands trembled, his eyesight was blurred, and his step faltered. The family ate together nightly at the dinner table. But the elderly grandfather's shaky hands and failing sight made eating rather difficult. Peas rolled off his spoon onto the floor. When he grasped the glass often milk spilled on the tablecloth.
The son and daughter-in-law became irritated with the mess. "We must do something about grandfather," said the son.
