Imagine a mother is waiting for his son's arrival at 1 am and her young son has not returned home yet. The family daughter says: let's call police or emergency center; maybe he has had a car accident! Mother gets angry with her daughter and wants to say; "stop talking / thinking about bad things / events etc." Does the sentence bellow work in this sense and does it sound natural and idiomatic? Is it in common use in the US?
- Don’t foretell dire things.
