I just got into an argument with my Dad while doing my Geography work because he thought that Russia and China were the same continent. I kept telling him he was wrong but he didn’t believe me so we made a bet and I had to google it and show him a map. Still  he kept consisting it was wrong claiming, “I lived in Germany as a kid and it wasn’t like that before." 

I won. He now has to make me sandwiches whenever I want for the rest of his life.
