Never trust the well wishes of foes
Once there was a wicked cat that loved to eat chickens. Everyday, she used to find a chicken from somewhere or the other and ate them up.
One day she came to know that a hen was ill. She went to her and asked about her welfare. She also asked if she could help her in any way.
The hen replied, "The best help you can offer me is to stay away from my family and convey this message to your race too."
