When I was a child I liked the story by Nikolai Nosov about a boy who was afraid of a black cat crossing. He changed his way and had a lot of problems because of his belief in superstition. This is a funny story for children but since that time I haven't believe in superstitions)
BUT:
I ussually have a season of broken cups when I take my exams at the University. In my country people say that broken things are to happiness. It's better to me to believe in this superstition than declare my excitement)
I ussually get wet. I can't miss any rain and often come home wet. My mum says that I will be rich because rain is to wealth. It's possitive to think on such way)) But I know that I ussually get wet because I have never take an umbrella.
