My mom always says:
Cuando suena el rio, es que piedras trae.
When sounds the river, is that rocks bring.
When the river sounds, its bringing rocks.
It means, when you hear the sound of water, it means a stream is going to come by. Like rumors about people. When theres something going on, their suspecting this guy for burglary, theres a reason to believe it. When you hear something, its really coming down. If people are saying something about other people, it might be true.
Sometimes Ill be like, theyre accusing this guy but I dont think its correct, Then my mom will say [the proverb], saying there might be truth to it.
This Guatemalan proverb is quite popular, and the moral of the story is that when you think you hear something, the impact is actually more than you think. Theres probably more to the story than you first think, so its crucial to take a step back and carefully consider the truth of the words.
