Or what if we take it by chance? Like, decide that one of us is an even number and one of us is an odd number. Then, let's take some number we don't know (say, exact size of Portugal in square kilometers, or how many hits do you get by googling some word, or how many posts 'downer x has or so on) and check what's it. If it's an even number, the one who's even number has to vote first, if it's an odd number, the one who's odd number has to vote first. Makes sense?
