I am taking online classes and had to report information about another country. I chose Ireland cause I've always wanted to go there. While looking at some of their folklore I found that some of the things are completely opposite of what is believed here in the US. the one that I am wondering about is this: According to the Irish folklore, A black cat crossing your path is GOOD LUCK! So how did this get turned around to bad luck here? Now I know that I'm talking about another kind of cat here(the 4 legged fury kind) but I am curious as to how things like this happen.
