Don't send shit other than letters. You'll only end up making his life a living hell. Also remember, the mail is fukcing slow.
All you newfangled squids and your cards and shit in boot camp. We had paper chit books in bootcamp. I think it had like $50 worth of "chits" all $1 each. I think I have some stashed in my cruisebook from bootcamp. Making playing cards out of the cardboard from the back of our notepads and playing tonk and guts with chits, ah memories
