A fool is pleased by flattery like the inflated heel of a corpse that has the appearance of fatness.
Take care not to listen to the voice of a flatterer
Who expects cheaply to derive profit from thee.
If one day thou failest to satisfy his wishes
He enumerates two hundred faults of thine.
Saadi Shirazi
