Yup - two complete strangers who I'd never met, never knew the existence of, who had closer family members. Why would I visit? Some weird sense of duty? Compassion? I could have feelings of duty and compassion for all sorts of people who I actually have a relationship with.
Why does it make a difference that there is a 'blood' link? The anti monarchy posters on here are always very dismissive of 'blood' links but in this instance it makes someone responsible for someone they've never met.
I'm sure there are many people currently in institutions who rarely receive visits (in fact I know there are). I'm assuming all you compassionate types are visiting people unknown to you on a regular basis.
