Those are both poor answers.
you thought you saw a team forming.
you are being asked to evidence that accusation.
You are unable to provide said evidence.
you find it hard to believe I am a vanilla.
you are asked for your own role in turn.
you are unwilling to provide it and instead answer in riddles.
A townies job isnt just to find mafia. Its also to provide to other townies that you are town.
Not answering questions does the opposite.
