You have just discovered that your teenage son has left to go shoot up his high school. If he succeeds, no one will blame you, because you’ve taken every precaution and raised him well; unfortunately, he just went nuts. However, you can still stop him. On the other hand, your daughter is serious about her attempt to commit suicide, and if she succeeds, everyone will blame you (but you won’t be charged with anything). You only have time to stop one of them; who will it be?
