Well that part was in response to your "they understand each other because they have the same lifestyles."
You don't need to understand lifestyles to be supportive. Military spouses are away from their families all the time. So are pilots and truck drivers, etc. Celebs mostly exist in their little cocoon because as mentioned, they cannot trust anyone from the outside unless they were friends before they got famous.
