I have an idea for a new game
Player B is asked by player A to do something. Player B doesn't want to do it and he trying to avoid responsibility. And then he makes his own request.
A: Could you do me a favour and send this message to Tom?
B: No, I can't find my phone. It seems that I forgot it in pub last night when I was talking to Bruce Willis.
Could you do me a favour and feed my dog?
I'll start:
Could you do me a favour and wash my car?
