If you live in the countryside, you will cry when your father dies. Why?

Maybe it's a local custom. We don't have such a statement here.

Also, is it possible that "crying dad" is just a sentence, and people are still called dad when they die? For example, if someone is crying about his dead father, others will say that he is crying about his father. It's not that I stopped calling my father after I died and called my father instead.
