Here in Argentina we have a lot of superstitos
Personally I believe that when youe left hear is red, someone is talking badly about you and the opposite with the other hear; I know of many times that this happened.
I think you've made a very good question, every place have its own superstitions, I don't know many of the ones here and there are many
I would like to know the ones you know (from your country)
there is the famous number 13, opening an umbrella indoors, walking down a staircase, the black cat (I have one); all of this bring bad luck
if you threat some fruit tree that you will cut it, it will give more fruits
That is wonderful subjact . but would any of you tell me where these superstitions come from . I mean, there must some reasons for it. these heritages must started one day in the past and I am sure they had many sensible reasons to believe them.
I have thought that superstitions may come from inhibitions parents give their children a long time ago, and that due to popular use and passing from one generation to the next, their meanings and even their structure eventually changed, and emerged as a path to having good luck or bad luck.
