After careful consideration, you decide to give your friend a hint.
You think of a word that relates to the word, but you think of two. You can't tell which one would be better to tell your friend. You then pick one and tell it to him.
After you whisper it to him, he thinks about it for a while.
During this time, you wonder if the hint you gave was good enough for him to understand the word.
A minute passes and then he has an idea.
You watch him carefully put his finger down and points at... the assassin card. The other team somehow gets their chain right and wins the game.
You then yell at yourself, I knew i should have gave the other word I was thinking of!
