In my country to speak of the “evil eye” is to recognize that there is evil in a person and that this person transmitted his evil in some way to a human being, an object, or a plant.

Thank you @wakeupkitty for tagging me.

The fact is that something that has the “evil eye” in the superstition, of course, can generate in that object its deterioration or that it is lost or broken.
When the same thing happens to a plant it can dry up, and lose its flowers or its fruits.
When it happens to a human being, he/she can get sick or even become seriously ill or die.

The truth is that everything is part, in my country, of people's beliefs. In my case, I must say that being a Christian I think that when we are under the shadow of the Most High we will always have angelic protection from everything negative in the world. Because I do not rule out that the envy of bad people can cause us harm.
