Assuming you live in a country that is not a dictatorship, how do you vote in your country?
Over here (well in my place montreal,canada) schools/church other buildings are converted to polling station. We get a letter that has the address of the polling station/number of box. We go get a slip of paper, black with white circles with the names of person/party to vote for beside it. We mark an X on that circle and drop it in the box.
