This was a film with Jodie Foster in it as a child. All I remember is her standing outside a house on a hill with trees and talking to some adult man about dying. And she had the darkest blue long socks on I had ever seen.
I've gone through her list of films and wiki and can't see anything that fits.

Could it be Echos of Summer?

Echoes of a Summer (1976) - Plot Summary

That looks like it is probably it. I mean I doubt she played dying kids in many films. :D Thank you very much indeed. I appreciate your help. :)

I hope it is.

If it isn't, I was wondering if you might be thinking of a Tatum O'Neal movie. (I haven't looked into her movies, yet.)
