A childhood belief about eyes

I used to believe that if we squinted during a storm, we could block our eyes, and my neighbor had a problem with the eyes that made him squint, and I was thinking he had squinted during a storm, So one day I asked him why he had squinted during a storm and he got upset and fought over me, I did not understand why he got angry and I understood 5 years later when I asked my parents if it was not true that we could block our eyes and that they told me that it was a myth to prevent children from squinting .Now I find this stupîd and I do not know how I could believe that for so long and how I could be so naive.
