Just because someone acts nice doesn't mean they have good intentions. All the serial killers have been described as nice. They are able to carry out their evil deeds because they have the charisma to make people trust them. Unfortunately the people who are naive and good hearted are the ones who become their choice victims. This lady is lucky to have survived but saying that you don't know wether she poisoned you just because you survived is beyond understanding, especially with so many people who weren't so lucky.
