Thank you very much!
I'll try to do an easy one since I will be away from the computer for a while. Once you know who it is, just go ahead and take the next turn.
In chronological order:
1. Never trust a guy with words tattooed on his knuckles.
2. Never trust a guy who wants to marry you only because he's interested in your young daughter.
3. Never trust a woman who would try to force her blind daughter into prostitution.
4. Never trust a religious fanatic whose son murdered a woman, even if your son was also involved in the murder, and even though you're running a 1930's dance studio together.
Who should have not been so trusting in 1 and 2, and should not have been trusted in 3 and 4?
