There was a king once that entertained 2 men from another kingdom. After they left a wise man visited the king and the king said “2 guys from that kingdom yonder came over”. The wise man said, “What did you show them." He said “Everything” to which the wise man said, “You fool, now they will come back and take everything”. Damned if they didn’t.

Moral of the story: Brag about personal things to people you don’t know and what you have may be taken away from you.
