The Viper and the File
A Viper entered a carpenter’s shop, and went from one to another of the tools, begging for something to eat. Among the rest, he addressed himself to the File, and asked for the favour of a meal. The File replied in a tone of pitying contempt, “What a simpleton you must be if you imagine you will get anything from me, who invariably take from every one and never give anything in return.”
The covetous are poor givers.
