The Hunter and the Horseman
A pedestrian hunter carried a big rabbit he shot in the forest on his back and walked toward his house. A horseman coming on a fast horse stopped beside the hunter on the road. The horseman said "My friend, give me the rabbit, let me put it in my bag; you ride behind me too, let me take you to your house." The hunter handed the rabbit to the horseman; however, as soon as the horseman took the rabbit, he spurred his horse and rode away fast, leaving the hunter on foot.
Falling immediately for the helpful-looking promises of people one does not know and handing over the concrete gain in hand is a great incautiousness. Believing quickly and trusting without investigating results in loss. Fancy words and promises of ease may carry bad intentions behind. Preserving the value in hand is better than leaving it to someone else's mercy.
Do not trust the fancy promises of strangers and hand over what you have. Fancy promise makes you lose what you have. Trusting a stranger is incautiousness. Promise of ease can be a deception.
Protecting the gain in hand is essential. Naively believing causes damage. One who does not leave precautions is not deceived.
