If I throw a birthday party at my house, and I suggest guests park a couple blocks away where there’s always lots of space, and, as my guest, you do that but get hit by a car when walking over, can you sue me for your injuries because my suggestion of where to park created a foreseeable risk of harm?

The California Supreme Court considered a question similar to that recently in Vasilenko v. Grace Family Church. There, a unanimous court drew a sharp line in duty of care cases involving premises liability.
