He also takes the boy on walks in the park and starts offering life advice that runs counter to that of Moses' father (who encouraged him to save his coins in a piggy bank, to become "rich").
Ibrahim, by contrast, encourages him to smile and ask questions rather than relying on books for answers.
His father (Gilbert Melki) is increasingly depressed and distant, insisting that the curtains remain closed because sunlight damages his book bindings (his library shelves are crammed full).
Each evening he arrives home, clicks off his son's rock music, chain-smokes, and downs laxatives (his failing bodily functions reflecting his emotional state), occasionally comparing Moses to a long gone older brother.
Ibrahim -- the sage, charismatic, and plainly desired father figure in this sentimental tale -- sees other details of Moses' daily existence.
