i love playing with cards, they're super fun! once, we tried to refurbish an old deck, but it got all mixed up, so we made up our own game with them instead. it led to lots of happy discussions and laughter. my friend tried to deflect when i asked about the secret rules, saying it's an undisclosed surprise for later. and oh, here's my preexplanation: i think surprises in games make everything more exciting!
