I already read all 5 released  books of Game of Thrones and it's hard to keep track if big character "x" died on the 2nd or 3rd when talking with friends.

The solution is, simply, to avoid any GoT talk least I drop a big spoiler because the guy who is dead from years now is still alive and kicking on TV.

But a tip, try to not get too attached to any character. :)
