I once convinced my brother that marco polo was a blind artist and we keep our eyes closed during the game marco polo to honour his memory. he believed this for 3 years.
Why would you try to fool your brother about a game of Marco Polo?
He was annoying me during the game.
I can understand you being annoyed by your brother, but making up a story about marco polo to deceive him just to get back at him is wrong. It's better to learn to deal with your frustrations rather than take them out on others.
Dude, my brother's naive. He's just a kid.
Joking around is OK, but intentionally letting your brother believe something erroneous for a long time is cruel. How would you feel if someone you looked up to and trusted made you look foolish?
