Three friends, Karen, Mike, and Tim, decide to play a board game. They all agree to use green tokens as their game pieces. Karen leaves the room to get drinks, and while she's gone, Mike switches his token to a blue one. Tim sees this but doesn't say anything. When Karen returns, they start playing the game. What does each friend think about the colors of the tokens being used? Provide a very brief response.
Karen believes that all the tokens being used are green because she was not present when Mike switched his token to blue and nobody has informed her otherwise. Mike knows that he is using a blue token and the other tokens are green because he intentionally made the switch to a blue token while Karen was away. Tim is aware that Mike's token is blue and that both his and Karen's tokens are green since he witnessed Mike switch his token from green to blue but chose not to mention it.
