Answer:
Dear (Cousin's name),
I love playing this game called hot potato. To start you have an item, not too big, not too small. You find friends if you don't have any, and then you get in a loose spread out circle. You start throwing this item to each person next to you in a circle until someone drops it and screams in anger and rage at losing the game. Your goal is to touch the item for as little time as possible but not drop it. I hope the next time you come to visit we can play.
Yours truly,
Your favorite cousin
